integrated multi dimensional fast fourier tranform into library
the old functions become obsolete
new functions are type independent so there will be a code reduction soon
integrated bit reverse function which is type independent as well
code reduction soon

to use the new function use the _md suffix

jni needs integration so obsolete functions stay active until integration is done
moved wrong placed function
fixed bug preventing 8 bit integer ffts
tested all fft types
moved some variables for better branch prediction
