[enhancement] Support for shortcuts?

[rkoe]

There are several apps which can be used to create shortcuts on the home screen.This is quite useful for e.g. quickly opening a text-file or for starting the "floating calculator" of the default calculator (which is currently not accessible with Silverfish).

Unfortunately, this does not work with Silverfish -- if a shortcut is created, it does not appear anywhere in Silverfish (but only on e.g. the home screen of the Trebuchet launcher). It would be nice if such shortcuts could be created (a) on the home screen and (b) in the app drawer.

So like this but with INSTALL_SHORTCUT. I think we'd need to change the database, but would be an opportunity to do so.
