Minor misc. fixes (#4729)

* [Simulator] Remove extraneous format value in microsTimer; Better way to delete SimulatorStartupDialog (in case no event loop starts).

* [Simulator] No helpers dependency for SimulatorStartupDialog.

* [simpgmspace] Rename micros timer function and make externally available.

* [Companion] Fix possible uninitialized value in TreeModel (compiler warning).

* [multi_arm] Fix minor compiler warning (MSVC: "unsafe mix of type 'uint8_t' and type 'bool' in operation").

* [lua] Fix compiler warning ("'data' may be used uninitialized in this function").

* [OpenTxSimulator] Fix analogs array range.

* [Simulator] Auto-start simulator when SimulatorMainWindow is first shown (vs. before it was shown).

* [Simulator] DebugOutput: prevent possible mutex deadlock on buffer overflow (force queued connection for Qt < 5.3).

* [Companion] Display calibration data for Horus joysticks (MOUSE1/MOUSE2)
