this is just so speed up compilation time & have some files
go away which have same names in qml viewer and quickdesigner.

The agent is only attached when creator request it.  But this may occurs
After some scripts have been initialized. Which mean we do not get the
scriptLoad call.

The idea is to only enable it if it is run with -debugger, but for now
it is always enabled for simplicity.

This let you debug QML Javascript from creator

This qmlviewer will be also the default one when opening qmlproject files
as the runconfiguration was changed too.

Also unify some method naming.
Use the new feature to add clear buttons to the Locator,
and the find tool bar.

Store threads and cache registers per thread in Snapshot.
As Trk does not generate Thread creation/deletion events.
try to add threads on the fly if a stop in a new thread id is reported.
Remove them in continue. Continue all threads in classic Trk.
Pass on state (crash reason) to ThreadData and model.
Factor out common code of both adapters to Snapshot/Symbian classes.

   Turns out that the filename of the project can still be empty
   when calling these methods from the new project wizard (before
   the first page is done).
