Greasemonkey: indent source of required scripts

Browse Source 
This is for the case where a script uses `@require` to pull down another
greasemonkey script. Since QWebEngineScript doesn't support `@require`
we pass scripts to it with any required ones pre-pended. To avoid
QWebEngineScript parsing the first metadata block, the one from the
required script, we indent the whole lot. Because the greasemonkey spec
says that the //==UserScript== text must start in the first column.
