This will allow all CUTSCENE events to use the ifcutscene command.
Before, only EVENT_CUTSCENE for ANM files could use it.

This reverts commit 33d4dc3d.

engine: remove wrappers around glBindTexture() and glActiveTexture() in favor of explicitly calling polymost_activeTexture() and polymost_bindTexture()

This is better for clarity, I think.

This should fix terminx/eduke32#16

Debug is now configured to use AddressSanitizer on 64-bit, and various other build options have been made uniform with each other across all projects. This means 64-bit debug builds built with Visual Studio will only run if the VS ASan dlls are in your PATH, but I believe this is fine as we don't distribute any VS builds.

I didn't test this.

You're gonna have to talk to me or read the source for full details on usage, sorry. These are also all still liable to change in future builds, either in name or in functionality.

The default value is 256 (GRAVITATIONALCONSTANT value from USER.CON + 80).
