09/09/14 1.05.00 - Studio API minor release

Important:

Studio API - Studio::MixerStrip has been replaced by Studio::Bus and Studio::VCA. The new classes do not have a release method, as their handles remain valid until the bank containing them is unloaded.
Studio API - Studio::System::getEvent, Studio::System::getBus, Studio::System::getVCA, and Studio::System::getBank now take a string path. Functions that take an ID are now named Studio::System::getEventByID, Studio::System::getBusByID, Studio::System::getVCAByID, and Studio::System::getBankByID.
Studio API - Studio::EventInstance::release no longer invalidates the handle immediately. The handle remains valid until the event stops and is actually destroyed. In addition, this function now succeeds even if the event will not stop naturally.
Studio API - Events with sounds triggered by parameters will now stop rather than going idle when all sounds have finished and the timeline cursor has reached the end.
Core API - The wide string argument of System::getDriverInfo () and System::getRecordDriverInfo() has been removed. These functions now return UTF-8 encoded strings.

Core API - Android - Reduced latency for devices that support FastMixer, see "Basic Information" section of the docs CHM for details.
Core API - Added DSP::setWetDryMix so any effect can have generic wet/dry signal level control.
Core API - Added 3D ChannelGroup support. A ChannelGroup is a 'group bus' and it can now be positioned in 3d space, affecting the mix for buses and channels below it. 3D Cones, geometry etc all work. Use ChannelGroup::setMode (FMOD_3D) to enable a 3D ChannelGroup.

Fixes:

Studio API - Fixed transitions to the end of a loop region failing to escape the loop.
