New redirect checker for arduino: avrgcc.
Manual: add a note about YouCompleteMe.
SyntasticInfo: more details about modes.  Minor cleanup.

This executes the code your files. This is probably fine if you wrote
the files yourself, but it can be a problem if you're trying to check
third party files. If you are 100% willing to let Vim run the code in
your files, set g:syntastic_enable_elixir_checker to 1 in your vimrc.
