Mix project/mix deps aren't loaded

[skosch]

Hi Arnaud, thank you for this wonderful tool!

I have everything working great, except when I save a file and it shows me errors, it looks like it's just compiling that file by itself, which leads to warnings like e.g. module Timex is not loaded and could not be found on use Timex. Of course, that shouldn't be a warning, since the mix dependency is there and the whole project compiles just fine.

I can run MixLoad, MixStart and MixStop without problems, but they don't seem to have an effect.

What can I do to make the rplugin aware of my mix context?
