Fix for "Input string was not in a correct format." in ProGrids 2.5.0f0

There is one unhandled exception in the file Assets\ProCore\ProGrids\Classes\pg_Util.cs.

To fix it, change these lines in method ColorWithString:

return new Color(
float.Parse(rgba[0]),
float.Parse(rgba[1]),
float.Parse(rgba[2]),
float.Parse(rgba[3]));

to this:

try {
return new Color(
float.Parse(rgba[0]),
float.Parse(rgba[1]),
float.Parse(rgba[2]),
float.Parse(rgba[3]));
} catch {
return new Color(1f, 0f, 1f, 1f);
}
