Add "x" to word field for advanced as well as regular search

[alanfgh]

On the Wall, user cojiluc writes the following:

ln the search box, there is a small sign x which can be used to delete the content at once. It could be helpful if one has the same thing in the advanced search boxes, specially when using touch devices.

I agree. Note, however, that the advanced search word field is narrower than the regular search field, so the x will be smaller and harder to press.

I'd like to work on this. I will check the code this weekend

Thanks a lot, @gioele-santi !

Yes, thanks for fixing this, @gioele-santi. Replacing the contents of the field is easier now.
