FS19 - Courseplay V6.4

ModDesc and icon prepare for ModHub
Some corrections and additions for modHub

fixes #7196 untill we have a better solution some day.
Some ModHub fixes
Changed Version format.
removed not used files
changed the fieldscan dialog, but would need a new line to be more clear, also don't know what error it created...
Remove mipmap from fieldScanInfo.dds even I don't see the reason for this as it is just 'not necessary'
mipmap fixes
Update CpManager.lua
Hopefully better understandable how this Info screen works.
fixed last texture problem
Create mouseMMB.dds
so much about we don't need this file.
