While devs are busy with new shiny stuff we have to clean some dust.

And there's a lot of it laying around. Client is still using libraries which was old many, many years ago; ASCompiler likes to crash linker at least once a day; there are problems with compiling... anything on newer Visual Studio, big parts of code are giving us headache, and so on, and so on... Refreshing development environment really needs to be done - by migrating to newer VS, using modern version of libraries, replacing deprecated ones with better solutions, restructuring some questionable designs, and basically anything which will make our lives easier.

This is side-milestone; which means it might be completed before previous ones, but will not be released before them.
