Renamed file with openMSP430 defines.

Defines file (memory sizes, HW mult, dbg, ...) renamed
from "openMSP430_defines.v" to "openMSP430_defines_template.v",
because it was usualy included instead of customised defines
file listed in *.prj file. And this behavioral could not be changed
with "-vlgincdir" (Verilog include directory) switch in XST.
