FRB Editor should show an error if the .dll's file version is less than the .gluj version

[vchelaru]

Currently if the gluj version increments, the built .dlls will not increment until new nuget packages are pushed. If a user builds the FRB editor from source and makes a new project, this causes confusion.

Their project won't compile and they have no idea why. To address this, the FRB editor could detect that the .gluj is newer than the .dll and could show an error.

Alternatively the FRB editor could just suppress generation for newer versions, but this would be confusing for users who are intentionally trying to upgrade.
