Evil Search and Clear Across multiple Windows

[naclander]

This is the same issue as #803 , but I will try to reword it to make it clearer.

In vim, searching for a keyword causes that keyword to highlight both in the current active buffer, as well as other open buffers that have other files opened.

In Emacs/Evil, one can achieve this same functionality with evil-search, except for the last part. Specifically, having all matches show up highlighted across all opened Windows ( where each window has a buffer with a different file opened ).

Evil should behave the same way as vim, and highlight all matches across all windows automatically. This could be extended by giving users the ability to choose whether to highlight just the current window, all windows in the current frame, or across all buffers Emacs currently has opened.

Naturally, evil-ex-nohighlight should clear all matches across all windows. Or again, the user should have the ability to toggle this.

I hope this description is a little more clear in regards to the feature request I'm describing.
