Added function to show line number
The function shows the line number of the first error/warning that appears in the current buffer. If there are 20 warnings and the first warning exists on line 33, then vim-airline would show "W:20(L33)". One can change how the line number is represented using: `g:airline#extensions#ale#open_lnum_symbol` and `airline#extensions#ale#close_lnum_symbol`
