Better mobile integration, avoid interaction with mouse in the form, minor fixes

This is a modification to make the search box look better and work better in the mobile devices, since its a little bigger and the borders are diferent. It also look better on every os, it also was a little broken with bootstrap (at least on my project).
I also fixed the problem when the user double click or click->hold->move mouse inside the form.
Some minor tweaks.

PS: My editor changed the tabs into spaces, this make the commit a little bigger. :/
