Use Leader-Enter for normal EasyAlign

I tried to use this map and assumed it was Leader+Enter instead of
C-Enter, so change the map to match my expectations.
Change pythonError to pythonBadStyle

I want to prevent me from doing these mistakes, but I can't fix them in
readonly files, so I don't want them to be so obvious. Changing the name
makes it easier to remove them but keeps the actual python errors
defined by other syntax files.
Setup unite

Add repo and add separate plugin for unite configuration (to keep it all
in one place). Maps are based on ctrlp.

Uses special script to get filelist (but it's really slow).

Installed some necessary plugins to replicate most ctrlp functionality.
