Further cancel and progress improvements

• Now cancel does a better job draining pending commands from OctoPrint while still being "immediate"
• Progress in 0.3.11 provided OctoPrint with too many "ok"'s which would mess up wait states later

More reliable positioning and LCD improvements

• Significant improvements in keeping track of where the bot is so that relative moves and homing work properly
• Report build start with name so it shows on the LCD
• Show OctoPrint's progress percentage on the LCD if gpx.ini has build_progress = 1
• Add @build NAME and @flavor FLAVOR macros

Really verbose logging

• Conditional clear queue on cancel
• Verbose logging works now (watch out, it is really verbose)
• Fixed build name in implicit M136
• Changed buffer overflow behavior to avoid hanging OctoPrint and shortened the pause to 100ms+python overhead
• Connection pause setting for bots that need it and to allow shrinking it for those that don't (used to be fixed 2 seconds)

Some new settings

New settings for connection pause, verbosity level and pre-release opt-in
Fixed a bug in the GPX submodule: G28 didn't work with X/Y minstops.
