Better header information on common.sh.lib
Clean up some typos.
Introduces 3 new functions:

generate_alphanumeric - create one random alphanumeric value
generate_alphanumeric_string - create a string of alphanumeric values
tmp_random_name - attempt to mimic mktemp's functionality, only creating a name instead of the file
Add note re: tmp_random_name being potentially unsafe and increase string count to 10 char.
Add prototype IncreaseAudioVolume function
Change CreateAudioPipe to use a randomly generated filename instead
	Needs further work to allow chaining between named pipes
Provide more details on EncodeAudio_FlacFlac (and rename)
Convert IncreaseAudioVolume to using a randomly named pipe
Have IncreaseAudioVolume clear the previous pipe too
More work on IncreaseAudioVolume. Seems buggy.
MEDIA_PIPE and LOUDER_AUDIO_PIPE should be local variables.
Add author and GPLv3 Header information
Add GPLv3 Header to common.sh.lib
Add GPLv3 Header to media.sh.lib
