Open command was not using system_path to ensure user expansion.
Testrepo was using pubsdir:// instead of docsdir://. Although not
directly used in test this was misleading and incoherent.
Also fixes missing system_path in filebroker.
Paths should be normalized through content.system_path before any actual
operation on files. This is in particular taken care of in content
functions check_file, check_dir, write_file, and read_file.
The Repository rename_paper method has been updated. The citekey update
and syncronization with citekey in the bibdata should be handled in a
sane manner inside the Paper class.
The error raised by Repository.push_paper was different depending on
whether the existence of the paper in the repository was tested directly
through the filebroker (quicker when list of citekeys in not loaded) or
through the regular __contains__ method.
* only bibtex format is supported
* all tests except test_repo.py and edit test pass
* edit and update commands were not updated
* removed --format argument from export, only bibtex is supported.
