Qt5: rename some files to fix windows build

If this works, I will have no idea why.
GCS: fix data type to qint16 instead of int16_t
GCS: update more uint8_t types to quint8
Building system:Apply all Windows 7 specific rules to all Windows versions
GCS KML:Compile fix, use "false" instead of "FALSE", remove EXPORT_PLUGIN
KMLExport: clean up the library includes
KMLExport: need to include uavobjectsinit.cpp

This is required for initialize all objects. I cannot understand
how this ever compiled before.
Qt5: bump to 5.2 release
RawHid: Mutex not correctly released in GCS

In the write thread it can short circuit out of the loop
without releasing the mutex. Using a locker avoids this.
This probably has no consequence since the mutex is
private to the write thread.

MainWindow: allow custom style again

Disabling this made the bottom bar look a mess. This fixes it.
