New feature release for Yapsy 1.11.023

This release brings one new feature:

Plugins can live in their own separate processes thanks to a contribution pylanglois (see the documentation at http://yapsy.sourceforge.net/MultiprocessPluginManager.html)

There was also a fair amount of cleanup, the biggest of all being the definite merge of the Python3 and 2 branches thanks to delijati.

In details:

• [contrib] Allow plugins to be run in separate process (https://sourceforge.net/p/yapsy/patches/6/)
• [contrib + bugfix] Merge Python2 and Python3 branch With Flask fix (https://sourceforge.net/p/yapsy/patches/7/)
• [contrib] Sets error if it fails to construct the object (https://sourceforge.net/p/yapsy/patches/5/)
• [bug-fix] PluginManagerDecorator.init defines a list and dict as default values in its arg list (https://sourceforge.net/p/yapsy/bugs/23/)
• [bug-fix] VersionedPluginManager needs to call _prepareAttic after setCategoriesFilter (https://sourceforge.net/p/yapsy/bugs/22/)
