Title: Fixing DTMF generation

From Audacity's src/effect/DtmfGen.cpp:
Note: added support for letters, like those on the keypad
This support is only for lowercase letters: uppercase
are still considered to be the 'military'/carrier extra
tones.

A-D keys must be uppercase, otherwise they will generate the tone for 2
or 3.
Added a call to tr in generate.sh to uppercase the letters.
This was only after spending an hour trying to debug multimon's DTMF
decoding...
