[geeklog-devel] Plugins and GL 1.5 online config manager

[Blaine Lang]

With GL 1.5 and the online config manager, plugins that want to use it 
have to do things a bit different and I've re-worked the staticpages 
plugin installation and upgrade code to support loading the online 
configuration. What's needed now is peer review to see if this is the 
best way as it would likely be copied into other plugins.

A few notes about the changes:
- Need to have an upgrade function that will create the online config 
records and use the existing plugins config.php settings as defaults
- Once upgraded to 1.5, we don't want to load the settings from the 
config.php. It really is not needed once upgraded or if a fresh install 
performed
- If upgrade is executed, the config.php file is renamed
- Added some new language defines for extra upgrade error messages and 
online config manager menu labels

- Install script does not include the config.php now
- Added a new file - install_defaults.php, so that initial defaults for 
online config records can be defined and not in the install code
- Added a new function in the install.php -> plugin_load_configuration()
