Migrate macro build to shared method

I have several databases now that use this component and have a need to
build both compiled and interpreted components.
At some point I added a macro to help with this...I'm not sure why I
didn't just add a method.
So I've converted this feature into a shared method and removed the
macro.
Other changes:
-Removed obsolete comment from version_template.txt
-Bug fix: BLD_BuildWithCompiled (in macro form) didn't check to make
sure $buildDestPath_t ends with a separator.
