change name TEXTE_MODULE::MirrorWithModule to TEXTE_MODULE::MirrorTransformWithModule, because it is a function specific  to a footprint transform in modedit.
change also name TEXTE_MODULE::RotateWithModule to TEXTE_MODULE::RotateTransformWithModule for same reason.
Pcbnew: fix Bug #1374484 (text changes position when module is flipped and rotated). Fix also some bugs in modedit, in block commands.
