4.29 -> 4.30 Change Log

(EV3) LEGO NXT Sensors that are normally auto-ID'd no longer have their autoID flag disabled for that port.
(EV3) Fixed an issue with the EV3 remote screen may have caused a ROBOTC crash.

(All) Rebuilt firmware to version 10.30. All platforms will require a firmware update.
(ALL) Prevent Graphical files from asking to save if the "Save On Compile" flag is set to false.
(ALL) Update all standard models to have correct drive train setting.

(ALL) Fixed an issue where a "sprintf' varArg list contains a string constant the compiler was generating incorrect code causing a firmware crash.
(ALL) Compiler Fix: 'long' pointer temporary variables were sometimes being allocated as type 'signed' instead of 'unsigned'.
(ALL) Checking for "divide by zero" exception forgot to check in the "module" opcodes; it was only checking the "divide" opcodes. Fixed.

(ALL) Fixed issues where the first time the Debugger "Local Variables" window is painted with values (rather than blank) the address field displays "0xCDCDCDCD" rather than the offset.
(ALL) Graphical Interface now support "multiple selection" using Shift/Control keyboard modifiers (drag select coming soon!)
(ALL) Fix for DebugStream which was adding \r to the String as it was written to file.
