Merge STYLE_DEBUG with SCRIPT_DEBUG
|Reported by:||nacin||Owned by:|
Defining STYLE_DEBUG by itself does not serve concatenated development scripts, because both scripts and styles depend on the same concatenation global (and overriding CONCATENATE_SCRIPTS constant).
It will serve the development version of colors, but that's about it.
I suggest we get rid of STYLE_DEBUG and change all of its references to SCRIPT_DEBUG.
The alternative would be to allow concatenation to be controlled independently, but that would introduce another global and change existing behavior, having an effect outside of debugging. Removing STYLE_DEBUG has no real downside and makes it one less constant for developers to define.
