Reconstruct stable code in master and streamline build configuration

[Pathoschild]

This pull request resets master to the last stable release for each mod, and adds changes to make the code easier to compile for other developers. This serves as a stable baseline for further EF 1.x changes.

The main changes are detailed below.

Changes

Reconstructed stable versions

• Reset master to the latest stable releases for each mod.
  We don't have the code for some of the mod releases, either because there are no commits until a later release (Entoarox Framework 1.7.4) or because their changes were mixed into the EF 2.0 commits (Seasonal Immersion 1.8.2 and Shop Expander 1.5.3). I decompiled their latest releases and reconstructed their code, so we have a stable baseline for EF 1.x changes.

  I assumed any code present before each mod's latest release date was part of that release. Per our discussion, I reset Entoarox Framework to 1.7.4 instead of the latest 1.7.9.

Simplified building the mods

• Added missing files from the latest downloads (mainly manifest.json).
• Updated the build config package.
• Moved the <GamePath> setting into a shared common.targets file.
• Enabled automatic deploy into the Mods folder on build.
• Enabled automatic release zipping on build in release mode.

Fixed errors

• Fixed a couple of compile errors.
• Removed old debug code that crashes if used.

Other

• Copied the README changes from the EF 2.0 branch.
• Incremented the Entoarox Framework version to 1.7.10 for re-release per discussion.
