Fix casing of filenames and code in plugins/ (#6350)
No functional changes! No changes to savefiles/presets! Fixes casing of everything that is currently lowercase but should be uppercase. Fixes also some other plugin strings, especially: * opl2 -> OpulenZ (see289887f4fc) * calf -> veal (seeae291e0709) * ladspa_effect -> LadspaEffect (see9c9372f0c8) * remove flp_import (see2d1813fb64)
