Merge branch 'release/0.4.2' into develop
Removed only bold statement left in IR_Black colour scheme.
Made SignColumn have a black background to match black term.

Before, this was a grey colour, which was a tad annoying. However, with
the black colour the indicators from syntastic stick out a bit more.
Plus there is no longer a long, randomly grey bar at the side of the
editor when an error is made.
Pressing 'gO' will now open the file under cursor in Mac app.

This is set to work only when working on a Mac.
Moved par formatting option higher.
Cleaned up vimrc bundles section a bit.

Changed vim-script/YankRing bundle to its idomatic Vundle syntax.
Added MoinMoin syntax bundle.

This is mostly a copy of the MoinMoin syntax file provided by the
MoinMoin wiki, except it no longer changes the colorscheme to the
default.
Added easymotion bundle.

This bundle is useful for simplifying movement commands. It highlights
how far a certain movement command will go, making it simple to do far
out movements.
Set up omni completion with SuperTab, use tab to expand.

This update allows for omni completion via tab in insert mode. In order
to make this compatible with UltiSnips, the key bindings for UltiSnips
were changed back the defaults. The exception for UltiSnips is the list
snippets key was changed to <c-k> in insert mode because <c-tab> (the
default) does not work by default in many terminals.
Added omni completion of Go code through a bundle.

This is really just a github, vundle-friendly copy of the files provided
by the Go installation.
Go code files are automatically formatted on read, spaces, width 2.

Go code is automatically formatted with tabs instead of spaces, and a
width of 2. This is performed on the read of a file, so saving the file
to disk will not show the changes in vim. To do so, reload the file with
:e.

The reason for not performing the edit on write was because doing so
loses the place that the user was at, bumping them up to the top of the
file.
Pressing 'K' in normal mode brings up Go documentation.

This applies only to files of filetype 'go'.
Bring up python documentation with 'K', like Go docs.

Works for only files of filetype 'python'
Updated README to reflect 0.5.0 release.

Releasing 0.5.0: Omni completion, code docs, autoformatting, and easymotion.
