Merry Christmas

This release improves over the first one by providing a much more faithful FF. It fixes some timing problems that should improve timing precission and avoid some problems. It should also provide best latencies on any situation. There's also some new features useful for user configuration tools.

The detailed changes:

• Fixed synchronism error that could cause higher latencies due to sending commands too fast.
• Avoided queueing of URB packets in the kernel which could produce high latencies and the error "output queue full".
• Added timer modes to dynamically adjust the period to different situations and get the best latencies.
• Added high resolution timers to improve precission of effects.
• Default timer period has gone from 4 to 2 ms.
• SYSFS entries for gain and autocenter (read/write).
• Global and application gain. Applications will have their own gain setting and won't override the global user setting.
• Gain now applies also to conditional effects. It was only working for the non-conditional effects.
