Bump version: 1.2.0 → 1.2.50
Send refactor RPC request args as a list.

The 'params' of the request was being set to the first arg. Since this was
a string (the project root path, specifically), the arguments to the
server methods were being set to the list of characters in the path. This
ultimatedly caused Emacs error messages like "error in process filter:
Invalid function 12345" when trying to refactor.
Merge pull request #153 from ericpeden/master

Rework refactoring callbacks to use the new asynchronous API signature.
Rework project root detection to always return a directory.

This used to return nil in certain cases to allow for "no" project root,
but the rest of the code did not work well with this. Now elpy just
issues a warning for a project root equal to the home directory.

This should fix #157.
Rename system tests to functional tests.
And => When in some feature tests
Add some compatibility definitions for Emacsen before 24.3.

This should fix #156.
elpy-rpc--call-blocking: Pass the RPC process to accept-process-output

When the PROCESS argument to a-p-o is nil, it will block for SECONDS
even if there is data available for this process. This is not exactly
what I expected reading the docstring, but that's what it is. Elpy now
passes the RPC process as PROCESS, meaning blocking calls will finish
a lot faster now.
