Cleaned up serial port libs, activated mav visualization on map (still debugging), fixed standalone MAVLink generator

The MAVLINK_MESSAGE_LENGTHS macro can be used to detect mavlink
messages that don't have the expected length. It is done as a macro so
that projects that don't want to pay the cost of a 256 byte overhead
can avoid the check

Made MAVLink parser aware of line breaks in comments, added new servo output packet to QGC and simulation, enabled servo output display in new Actuator View (previous Payload view)

Improved line chart, brought back movement on HUD (but still looks somewhat wrong on the dials). Fixed logging for ground time mode

I added the ability for the parser to pack an array of any mavlink standard type.  This will allow array types to be specified for mavlink messages without using the type="array" syntax.

I also changed how a bunch of the strings were constructed to more closely conform to the coding style guidelines by reducing the number of implicit copy constructor calls

Made generator --pedantic GCC flag compatible/C89 compatible, fixed a bug where heartbeats where only sent to first link

Started to add support for autopilot firmware updates, added Linux compile instructions, fixed date in mavlink.h to english independent of OS language settings

Added support for MAVLink XML inclusion, added support for multiple Autopilots, improved protocol generation

Currently testing parameter write, close to completely working, created beta release binary from this state
