Update version in debian/changelog.
Engine: fixed division by zero in alpha blender

The dvision by zero was occuring if the custom alpha supplied was of very low value.

DeserializeConvertValueAttribute attribute is applied to serializeable Type; if a property of that type is being deserialized, these attributes perform value conversion, if required.
Engine, Editor: an option to disable key shortcuts in dialog options
Engine: introducing macro for extended keycode shift value
Engine: changed built-in key combo for displaying runtime info

This changes hard-coded key combination for displaying engine runtime info from Ctrl+V to Ctrl+Alt+V
Engine: temp fix for OGG & MP3 voice buffer underrun

This is a hotfix for voice clip stopping playing on rare occasion, when the OGG or MP3 decoder encounters buffer underrun.

AGS uses ALOGG and ALMP3 libs as intermediate between itself and OGG/MP3 decoders. Unfortunately, it seems that these libraries do not provide means to deal with situation like that properly. When streaming, instead of pulling the data from source, the simply wait when the user would push some data into their buffers and polls, in contrary to how underlying decoders work, making it impossible to interfere in time if the buffer underrun was detected by the decoder.

This fix only forces the playback to continue. A drawback is that a tiny chunk of audio data is dropped, making very short, but noticeable pause in speech.

The proper solution would be to upgrade ALOGG and ALMP3 libraries to the latest version with more clear streaming API. This would require to change how AGS works with them, so I am leaving this for the future major version (3.4.0 or higher).
