Adding a plugin that shows differences since the previous reversion in
the left column (gutter)
uploading gitmodules for gitgutter. tweaked the keybindings and
settings for diff so its settings will be enabled by default when it's
being used regardless of where it gets initiated, and won't be used at
all when it's not initiated. Improved vimdiff settings in general.
Improved the help popup tab (it's now sized exactly to the width of the
help page). The theme now takes colour hex codes with or without #s at
the start so they can be used with the coloresque plugin to show the
colours while editing. The theme now considers gitgutter. vimdiff now
uses <leader>> and <leader>< to make a change because I realized the
current way was leading to changes being made when you reversed
direction.
Added more consistent signs to gitgutter and tweaked the theme a touch
