Version Checking Improvements and Upgrade Fixes

This is a minor bug fix/improvement release that addresses two things that should have been in the last release:

• Links to fractal forum/nexus mods posts if they are included in the .version file of a mod.
  • Clicking a link will open it in your system default browser.
• Fix: Installing a mod with a conflicting ID/upgrading a mod now works as intended.
  • This was not working as intended on release.

As usual, please find binaries attached below, under Assets.
