Add ability to use tab to complete like IDEs and youcompleteme

Not sure if this is worth implementing or not but might be useful

Well, my installation is working with tab completion. Maybe it's supertab working over it tho.
But i have to say, this is blazingly faster than youcompleteme. I didn't have time to test it further, but the only missing link is the fuzzy-matching. But even then, i would change fuzzy matching for speed.

That's weird. I'm not using supertab, but I do have this in my .vimrc

set expandtab
set softtabstop=4
set shiftwidth=4
set tabstop=4

Pressing tab just inserts 4 spaces when the completion window appears by itself

Well, as far as i know vim by default doesn't use tab for walking over and back on the popup list, instead one should use C-p or C-n. However, one can emulate the tab behavior by mapping it to those key binds, which is exactly what supertab does.
Regarding your configuration about tab, as far as i know it doesn't have anything to do with popup completion. It is just for tabs when used in insert mode, which is what you are doing it(hit tab get 4 spaces).
