change way playlist is played and created

[sq6jnx]

Steps:

• modules should return messages as it would be written by human
• (possibly) TTS-specific routine should change it into list of samples it knows
• if message contains samples which are not words (CW, beeps, etc) it should be noted in playlist (ie. as file://path/to/file

Thoughts:

• module-specific translations shoud be placed in a separate file
• statics, like numbers, should be placed in one variable (dict() maybe)
