...and added a TeXworksLaunched hook in r726.
A few notes:
* The hook is run with an invalid (=null, none, nil, whatever) TW.target
object, as there isn't necessarily any window open at the time
* In case a second instance of Tw is executed (and terminates
immediately, due to the single instance code), the hook is not run again
* In case files are passed on the command line, these are opened before
the hook is run. Thus the LoadFile hook may be invoked before the
TeXworksLaunched. Special care must therefore be taken in scripts
implementing that hook.

Testing builds will be updated soon. Hope I didn't break anything ;).
