Title: Supress tab numbers and improved uniq_tail formatter

Hi, in this pull request:

1. g:airline#extensions#tabline#show_tab_nr - allows to hide tab numbers in tab mode
2. convert slashes in buffer name from windows to unix style;
3. New formatter "uniq_tail_improved"
- works in tab mode;
- process only buffers with non unique file names;
- shows only different parts of path, compact similar path tokens to '...', for example, if we have following four buffers opened:

buffer path	buffer displayed name

zzz/vvv/fff/app.txt	zzz/.../fff/app.txt

zzz/vvv/xxx/app.txt	.../xxx/app.txt

ccc/vvv/fff/app.txt	ccc/.../fff/app.txt
