update entities.def files with latest classname changes
introduce g_debugEntities, which is currently only capable of silencing warnings with negative values

deprecation warnings will not be printed with -1
and -2 will get rid of spawn errors (maps might still partly work if we ignored these willingly)
add some form of explicit version-statement per entity class
differentiate deprecation warnings based on a combination of g_debugEntities and the versionStatement
fix trigger_touch being not sorted correctly within the spawntable therefore breaking all suceeding named entity spawns
