Mod version conversion error

[PaulCanada]

SDVMM does not handle semver's versioning rules, and as such, causes an unhandled exception when deactivating mods that follow semver's rules. Semver link

For background, with SMAPI 1.x mods specified their manifest version like this:

"Version": {
   "MajorVersion": 1,
   "MinorVersion": 0,
   "PatchVersion": 0,
   "Build": null
}

In SMAPI 2.0+, the recommended format is:

"Version": "1.0.0"

SDVMM supports the older format, but doesn't support the new one yet.

This bug prevents me from deactivating mods with a double click. The error prompt pops up after the initial selection. Is there a workaround?
