And load vimtex automatically. I discarded the autocommand as vimtex
only loads a small ftdetect script for tex and the rest of the plugin is
made up of ftplugins, indent files, etc. by itself.
The overhead of the autocmd feels bigger than just loading the small
component and letting vim doing the rest.
(But this is in now way tested/benchmarked. That is just how I feel and
it makes it a tad cleaner)
Instead of only sourcing the vim config when vimrc or $MYVIMRC (xdg.vim)
is edited, reload always when saving a vim file.
This is a test. But I think it makes sense since I never edit a vim file
that is not sourced by my config in any way. Thus reloading should be
always appropriate.
