Fixing issues reported by Tim Hosey at Mathworks: fixed check project button by making getFileState function use the client root instead of a list of files for large file sets.
Also investigated error messaging formats and determined that they and the "could not create new file" error are both controlled by MATLAB and not P4Simulink. All calls to "p4 reconcile" will strip the "No file(s) to reconcile." message as well.
