BF: demo now uses TrialHandler,importConditions
BF: Missed adding new .xlsx file in last commit
ENH: wav2flac: reduce default compression level (faster)

and expose the level; 0=fastest, 8=slowest
BF: Fix ignoring stimOut when saving data output

The methods saveAsExcel(), saveAsText() and indirectly printAsText() did
not use the lists from stimOut parameter. This prevented removing single
attributes from data output because by default every attribute is added.

This was an older problem. There may be working programs using the above
methods but actually pass not valid arguments. This did not matter until
now because the argument was ignored. Depending on the argument this may
raise errors (e.g. unrelated types) or cause less attributes written for
output (e.g. a former ignored list with less attributes than available).
ENH: Fix typos in source comments
DOC: Fix typos in documentation
DOC: Update documentation

importTrialTypes() is deprecated. importConditions() should be used.
