[ffmemless] Clear old effect before uploading new

If a effect with different type than an existing effect in kernel
is uploaded with same id, the effect loading fails. Solved this by
deleting the old effect before uploading new ones.

[ffmemless] Allow effects to be defined as touch screen related

Added new configuration option for effects that allow them to be
classified as touch screen related. For touch screen related effects
the touchscreen.vibrate.level is followed to determine if the effect
should be played or not.

The option can be enabled in ffmemless configuration file by adding
a "_TOUCH" postfixed configuration line. E.g. one could define NGF_SHORT
to be a touch screen related effect by adding to the .ini file:

NGF_SHORT_TOUCH = 1

[canberra] Fix memory leak and optimize silent playback.

If event has sound.volume property with value 0, don't really play the
sample but call complete immediately.

Also previously canberra plugin called n_sink_interface_complete() from
canberra_sink_play() where the request is not yet in playing state and
calling complete doesn't do anything. Added completion callback which is
called after plugin is in playing state.
