Fixed resource path dependencies issue that caused PARPG to crash on start. * PARPG should now run without issue (system installation not tested). * Utilized FIFE's VFS module to remove path dependencies from most PARPG modules. * The new parpg.vfs module is a singleton with a single global variable, VFS, which is a reference to the global VFS instance. Although a singleton is not ideal it should be replaced once PARPG's core code is refactored. * The parpg.vfs singleton is initialized in the parpg.applicaiton.PARPGApplication class with the absolute path to the data directory via the parpg.settings module and corresponding configuration file. * A new DataPath entry was added to the default system configuration file template under the [parpg] section to support the new parpg.vfs module. * Updated the parpg-assets subrepo to revision 3 to fix some dialog file format issues (for details see commit message for parpg-assets). * Fixed a few bugs in the parpg.dialogueparsers.YAMLDialogueParser class related to exception handling.
