Duplicate ids in Mercurial, Bazaar.

It might look a little bigger, but since we are using
QPushButtons by default in the options pages it's more
uniform considering the buttons around.

If we "conclude" it looks weird or unpleasant in other
places (like in the wizards, for example) we can consider
an alternative approach.

We decided to have text-based buttons by default.

This reverts commit 561f87fc.

This reverts commit c5b57ea5.

Add infrastructure for custom special stops with data.

Avoid writing empty string prefixed arrays into settings, and some
isNull vs isEmpty confusion (xml reader seems to read null instead of
empty strings in some cases).

To achieve this there are two methods in IRunControlFactory you
need to implement:

1) createRunConfigurationAspect returns a IRunConfigurationAspect
which stores the settings specific to your plugin.
2) createConfigurationWidget returns a RunConfigWidget that will
be shown in the project settings
