…e older BASS 1.x API because BASS_Init() changed the number of parameters. Use BASS_GetVersion() to automatically detect older vs newer BASS_Init() so interception works in both cases.

allow KKapture to compile whether you use VS2010 or VS2022.

KKapture 1.02 has been unable to capture some older demos because the older demos use a version of BASS.DLL where the init function has four, rather than 5 parameters. However there is a BASS_GetVersion() function which can be used to auto-detect whether the demo uses the newer or older BASS.DLL to avoid this crash.
For whatever reason KKapture 1.01 and earlier had no problems with the same older demos.
This fixes "Liquid Wen", "Mikrostrange", and anything that uses the older BASS.DLL interface.
