Also introduce a indirection, modes have now types, edit and debug have
the same type, and editors do have a prefered type of modes instead of a
prefered mode.

That fixes the bug that if the prefered qml editing mode was set to
design, then in switching between qml editors would
- in Edit Mode: stay in edit mode
- in Debug Mode: switch to debug mode

Set the variable to force the RVCT version when building for
Symbian using SBSv2. This is currently hardcoded to version 2.2
since we do not yet support RVCT 4.

Now that we have 2.0 out we can be less strict when checking
project consistency when loading .user files.  The strictness
was necessary due to upgrading non-target projects to target
projects.

 * Allow for invalid Qt versions when loading a .user file that was not
   updated from the pre-target era.
 * Update the UI to show invalid Qt versions as invalid. Remove
   the Invalid version as soon as a valid one is imported.

This does preserve the buildsteps, too.

 * Add more information into the updated map of .user-file data:
    * Version from which we updated
    * File name of the old .user-file we saved away

 * Make the keys available to projects from as constants defined
   in ProjectExplorer::Constants
