Force plug-in activation for custom property testers

This change ensures Eclipse correctly uses the property testers
'isBashFileWithoutExtension' and 'isOpenPathActionEnabled', by setting
the 'forcePluginActivation' property in the respective plugin.xml
entries. This allows Eclipse to load the property tester class prior to
trying to use it - in case the bash editor plug-in was not activated
yet.
