Minor enhancement to the visual theme resource enumId so that a more verbose name of the resource or template file can be specified.
The suffix in the enum contains following changes.
1. STYLESHEET is replaced with CSS
3. LOC is completely removed from TMPLT, since it is anyway specify a template location.
With all above points the total char size of the enum decreased and it gives an opportunity to specify better names and hence more readability.
For example VT_HDR_TMPLT_LOC becomes VT_HEADER_TMPLT
