Refactors meteor to have a resolve function that detects/filters out empty files (like for other managers).

Refactors manager.resolve to use file name to manager mappings.

Changes the way Renovate treats renovate config inside `package.json` files. Before, config used to be applied only to that particular file, meaning that it was not applied for the rest of a monorepo, or for other package managers like Docker. Now, any `renovate` section inside the repository’s root `package.json` will be applied globally, just the sams as if it were contained within a `renovate.json` file. This means there is no longer any case where you *must* have a `renovate.json` file instead of `package.json`.

Closes #1323

BREAKING CHANGE: renovate config in `./package.json` is now applied to whole repository, and renovate config inside non-root `package.json` files is now ignored.

Adds a new configuration option that allows you to bump the version number in the package.json being updated. e.g. you might configure Renovate to bump a patch every time, or maybe for dependencies only and not devDependencies. e.g. if you configure `"bumpVersion": "patch"` then a Renovate PR updating a `package.json` that used to be version `1.2.1` will now see it updated to `1.2.2` (in addition to the dependency version(s) being updated too). Thanks to @gunar for the feature suggestion.

Closes #861

This feature adds support for pnpm shrinkwrap.yaml files.

Closes #1391

Adds new configuration option “pathRules”. pathRules is an array of path rules. Each rule should contain a “paths” array which uses string or glob matching like the existing ignorePaths. If any of the paths in a rule matches a packageFile then the remaining configuration from the rule is applied to the packageFile.

Previously, if someone updated a package.json to include invalid JSON, Renovate fails to parse it (as expected), so ignores it. As a result, any existing PRs would be autoclosed. Instead, Renovate will now skip the repository and raise a warning issue until the file parsing is complete or the file is added to Renovate’s ignore list.

This PR updates Renovate to detect config validation problems and (1) stop processing, and (2) either raise an Issue if already onboarded, or (2) update the onboarding PR to reflect the error if still onboarding.

Closes #1300 

This PR adds support for bazel WORKSPACE package files, as suggested https://github.com/alexeagle/angular-bazel-example/issues/17#issuecomment-349167982

Renovate will:
1. Detect `WORKSPACE` files anywhere in the repository
2. Look for all `git_repository()` sections in the file
3. Extract any dependencies with name, remote and tag values
4. Look up any dependencies that (a) have a github https remote, and (b) a valid semver as tag
5. Update the tag to the latest available

This PR adds support for renovating the `node_js` versions in `.travis.yml` configuration files. Important notes:
- Functionality is disabled by default and hence opt-in via configuration
- Added a new manager type `node` because it is anticipated to support more than just Travis in future, with mostly unified logic
- Added the config option "policy" with supported values: lts, active, current, lts_latest and lts_active
- Policy is actually an array, to allow additive combining, e.g. `["lts_latest", "current"]`
- Actual node versions are *hardcoded*. There is no perfect metadata source for this and they change infrequently enough that it is definitely not a problem for now (next change will be in April 2018)
- If node versions need updating, they are listed from newest to oldest
- Replacing function attempts to detect the indention (spacing) in file and use that

To enable, configure `node.enabled=true` and optionally `node.policy=["<policy>"]` if you want something other than `lts`.

Closes #1208

Use `upath` for windows-friendly path joins.

Closes #1203

* refactor: don’t store yarn.lock content in packageFile

* chore: don’t log full lockfile

* refactor: don’t save package-lock.json

* update tests

Speeds up monorepos substantially

Remove original getFile, getFileContent, and getFileJson and replace with getFile (which used to be getFileContent.. shortened now for convenience). Also remove unused getSubdirectories functions.

Repository logic code has been rearranged for better logic and file separation.

Closes #654
