Hack to make SyncTeX work with zathura for now.
Install and configure the mighty Unite plugin.

Vimproc is a dependency of Unite, if it is to replace CtrlP, YankRing and the like.
Remove -no-split from Unite mappings.

Having -no-split makes the unite window appear in a full window. When I
exit the unite buffer, I am left with a blank window staring at me. It
doesn't go away automatically. Removing -no-split is a temporary fix.
Fix SyncTeX forward search with zathura.

I believe the recent update of zathura removed the '-s' argument. It
broke my mapping.
Add .latexmkrc, the config file for latexmk.
