* First version documentation PCM.info() method.
* Add reference to documentation to docstring for PCM.info() method.
* Add extra fields to info dict:
card_no *index of card* integer (negative indicates device not associable with a card)
device_no *index of PCM device* integer
subdevice_no *index of PCM subdevice* integer
and update documentation accordingly.

* Use `pcmtype` keyword for range
Update methods that accept a `direction` argument (i.e.
capture/playback) to get this via positional _or_ keyword arguments.
Code using keyword arguments can be more robust; however the main reason
for this change is to prepare the way for an extra `units` argument to
many of these methods.
Update documentation to consistently use `pcmtype` instead of
a mixture of that and `direction`.
* Support units
SND_PCM_FORMAT_S24_LE and similar are for 24bit ints packed in 4-bytes each.
There is a similar family of formats for 3-bytes packed data (as stored in 24bit wave files).
This commit:
- adds S24_3LE, S24_3BE, U24_3LE, U24_3BE PCM formats to the alsaaudio.c
- updates documentation
- updates playwav.py to correctly play typical 24Bit PCM wave files
Closes#38
- Avoid internal re-opening of PCM objects when parameters change.
- PCM objects can be opened by card id
- Mixer objects can be openend by card index
(this is not consistent, but ALSA works this way)
- Adjusted and cleaned up documentation.

setup.py was extended for pypi.
doc/index.html is automatically rewritten by doc/src/Makefile to add
SourceForge links. index.html is now the standard homepage for pyalsaaudio.
Minor documentation fixes (capitalisation, spelling, etc.). Caspers email is
hidden in the documentation.
