Handle SymrefLoop. Fixes: #293

Support 'main' as a default branch name to try.

Fix InternalServerError when viewing history of a blob.

[ci skip]

This should fix exceptions with undefined newblob, when there's a submodule that's the first path in the tree.

This at least allows rendering pages rather than throwing 500s.

* Actually test blame in blame tests.

* Prepend to PYTHONPATH rather than overriding it.

This is convenient for those of use that e.g. pull in httpauth through
PYTHONPATH.

* Support viewing blame of empty files.

Without this, klaus tries to access repo[b''] which leads to a KeyError.

* Update runtests.sh

Check that README is actually a blob, not a tree

repo.py: fix cloneurls showing up as b'http://example.org/foo\n'

Simply converts all known readme naming conventions and file names
within the tree to lower case on file discovery. This ensures double the
coverage of acceptable readme filenames.

This patch is the result of a discussion over making the known readme
naming conventions extendable by the user on the Klaus mailing list.
