Removed ugly hacks for golang. Split the go.vim settings file out into an ftplugin for lang-specific and vim-go.vim specifically for vim-go settings.
Changed lightline theme and customized the filename display to include the parent directory.
Added some interesting iTerm2 colorschemes I found from https://github.com/mbadolato/iTerm2-Color-Schemes. The solarized one is higher contrast and looks better, and the monokai soda theme goes really well with molokai in Vim.
