refactoring DB plugins Part 1 - broken now - will fix tonight (issue
#121)
QT signal processing triggered before tests end (issue #129)
moving db trace, bug report and unit test to maintainer plugin repo
moved statistics sql statements to statistics plugin (#121)
adjusted statistics to peer IDs
statistics: minor log fix
sending db conn ready after plugin activation (issue #130)
statistics properly disconnect after deactivation
DB Connection Settings: Standard connection cannot be changed via GUI
Moved the statistics stuff from db plugins #121
moved reusable DB stuff to iface_plugin

*by calling add_supported_dbms in __init__ of a plugin the db
functionality of a plugin gets activated
*a class that handles statements for a special DBMS is then
reinitialized every time a db connection changes
Adding history to sql interface to test introduced db functionality
removing installer directory - everything moved to lunchinator-dev
adding requirements section to yapsy plugin files - displayed in about
plugins
Add sending time to waitingForAck dict
restored lunchinator.desktop
