Title: Hover speed-boost

Improvements to the speed of the link "hover" highlighting.

A new variable `b:link_index_list` was created for this task.

" example:
" on line 55, extract link/anchor #2
link = b:tag_list[b:link_index_list[55][2]]

This may also be used to speed up link searches.

**Note**: `matchadd( ... )` is slow. Therefore, `matchadd` is only called if necessary. If the cursor is still within the previous highlighted zone, nothing is changed.
