* add gpg public key for package releases
* update watch file to look for key signature
* remove typos from library plugins
* change copyright to match dep5 format
* remove call of ldconfig in package maintainence scripts

    g_pool and g_factory global variables have been replaced by static methods
    getInstance in each class.
    getInstance returns a pointer to the unique instance of the class and
    creates it if needed.

      Remove pool::getSignal().

Added more exception catch codes in interpreter. Should now link correctly with boost libraries. Small debug output changes.
