add "clear search" button to FARR

[masu]

Hi,

please add a "clear search" button to FARR, so the user can easily delete his search word, if something was wrong

just hit escape and it will select your entire search string so you can start typing something new over it -- no need to use mouse.

ps. ctrl+backspace will delete last word.

thanks for the hint
