* #4627 - When looking for template files also look in the libraries subfolder of the supplied templateFolder, before checking the embedded locations. * Reworked the order in which template files are searched for: - 1st the code will check if there's a <template folder>/libraries/<library> folder containing the file - 2nd it will check for the file in the specified <template folder> folder - 3rd it will check if there's an <embedded template>/libraries/<library> folder containing the file - 4th and last it will assume the file is in <embedded template> folder. Added unit test to test template dir overloading.
