Added the option to the user clear the highlight by himself:

[eduardoHoefel]

joined s:clear and 'set nohlsearch' in a function called
no_hl_clear();
on_cursor_moved now calls no_hl_clear;
added a public function called Do_clear_highlight that
calls no_hl_clear();
I'm beginner at making vim scripts, so please modify
the changes to fit the right way of doing it
(if you want to merge the function, of course)

I like to use this feature too - accepting it is in plan?

I'm not actively maintaining this project (adding features, etc.) as I feel there's a fundamental flaw in the current implementation though I still use it. For now I suggest that you use the fork.
