emit FORM_ACTIVE, when form element follow.js'ed

Due to Uzbl removal it is no longer possible to emit event from js script. So
follow.js does not emit FORM_ACTIVE event, when user selects form element
using follow.js. Workaround for that is to run follow.js from shell script,
set some global variable and next read this variable from shell script.
