v1.1.24.03

Fixed COM exception messages to not end in `r.
Fixed {U+x} to support supplementary characters (x > 0xFFFF).
Fixed class properties which lack get{} to return an empty value instead of the internal Property object when the class has a base which does not define a value for the property. Properties defined in baseless classes already behaved correctly.
Fixed the background color of controls on a Tab3 control when the system has visual styles disabled (i.e. Windows Classic).
Fixed handling of thread-exit in functions which are called directly by an event (such as OnExit functions). This bug had no known effect except in the v2-alpha branch.
Fixed the debugger to detect disconnection immediately (i.e. when a client terminates without calling stop/detach).
Fixed the debugger to treat property_get -m 0 as "unlimited", as per the DBGp spec.
Fixed the debugger to expect base64 for property_set -t integer/float, as per the DBGp spec.
