//bme2ac by ryuuou
//takes a bunch of bms/bme files and produces .2dx and .1 files (hopefully) usable with beatmania iidx ac
//!!!WARNING!!! THIS WILL PROBABLY FAIL HORRIBLY ON 64BIT PLATFORMS!!! Then again it might just work

//still unsupported:
//	- songs with missing wav files?


//Changelog:
// v0.7
//	- chargenote support for Sirius
//	- speedups
// v0.6
//	- greater accuracy in case of many bpm changes
//	- proper longnote handling support (both channel and lnobj)
// v0.5
//	- partial support for freezenotes
// v0.4
//	- speedups
//	- implemented #STOP events (_NOT_ #STP events!)
//	- fixed a potential problem with fractional bpm
//	- fixed a bug with file names that have '#' in them
//	- the measure line of the last measure wasn't written out correctly
//	- nixed decrypted.2dx; encrypted.2dx -> output.2dx
//	- songs now end 3 seconds after the end of the last measure
//	- added several tools:
//	  create2dx_new, crack2dx_new, timebase_single, encrypt2dx, merge1, parse1; with sources
// v0.3
//	- killed debug output
//	- standard events are now written after bpm corrections to avoid screwing with the end-song event
//	- keysound preload events are now dynamic and always placed between keys; this should fix wrong keysounds on fast repeats once and for all
// v0.2
//	- implemented bpm changes
//	- implemented changing measure sizes, this should fix a lot of offsync songs
// v0.1
//	- initial release
