Traipse Beta 'OpenRPG' {091125-00}
Traipse is a distribution of OpenRPG that is designed to be easy to setup and go.
Traipse also makes it easy for developers to work on code without fear of
sacrifice. 'Ornery-Orc' continues the trend of 'Grumpy' and adds fixes to the
code. 'Ornery-Orc's main goal is to offer more advanced features and enhance the
productivity of the user.

Fix to Splitter Nodes not being created
Fix to massive amounts of images loading, from Core

Minor changes to allow for portability to an OpenSUSE linux OS
Miniatures Layer pop up box allows users to turn off Mini labels, from FlexiRPG
Zoom Mouse plugin added
Images added to Plugin UI
Switching to Element Tree
Map efficiency, from FlexiRPG
Added Status Bar to Update Manager
default_manifest.xml renamed to default_upmana.xml
Cleaner clode for saved repositories
New TrueDebug Class in orpg_log (See documentation for usage)

Pretty important update that can help remove thousands of dead children from your
gametree.
Children, <forms />, <group_atts />, <horizontal />, <cols />, <rows />, <height
/>, etc... are all tags now. Check your gametree and look for dead children!!
New Gametree Recursion method, mapping, and context sensitivity. !Infinite Loops
return error instead of freezing the software!
New Syntax added for custom PC sheets
Tip of the Day added, from Core and community
Fixed Whiteboard ID to prevent random line or text deleting. Modified ID's to
prevent non updated clients from ruining the fix.
