Reorganize vim plugin settings

Setting everything during PlugLoad function caused some plugins to
misbehave. Plugins are now loaded by Plug and their settings can be
either set with a file in the plugin directory (this mimicks the old way
of setting plugin up during load) or in after/ directory, which sets
options *after* everything has loaded.
