Update to vim-fixkey 0.3.0 (support for more modifier keys).
Update tagbar to a newer version.

This has the fix for autocmds being disabled.  We can now remove our
hack to make sure that Powerline is updated correctly.
Merge branch 'update-tagbar' of https://github.com/jszakmeister/vimfiles
Remove inadvertent select-mode printable mappings.
Use nnoremap instead of nmap for <Leader>fe.
Move SmartOpen into the core.

Dropped the SmartOpen command, since I never used it.  Also, the visual
selection was not working correctly (the function would always be
invoked with normal mode active), so I fixed that as well.
Implement better URL extraction.
