* Require CMake version 2.6.1 on Windows and version 2.6.0 for other systems.
* Update FindSubversion to version from CMake 2.6.1 (localization issue solved).
* Remove FindwxWidgetsCVS and use the default one (some issues solved upstream).
* Formatting style changes.
* made schematic loading of 'GLabels' dependent on the schematic file version (currently at 2).
If the version == 1, these are loaded as hierarchal labels
* made text labels global in the herarchy, consistent with their historical usage.
