make version string show commit hash

[ebrahimebrahim]

The version string for development versions should really show the commit id

We can make a git hook that puts it in before committing

Probably would be easier to have the version string be in its own file, and Globals.gd reads from it

Now I have a different idea of how to do this. Instead of git hooks, we write a script that uses command line to build:

https://docs.godotengine.org/en/stable/getting_started/workflow/export/exporting_projects.html

The current commit hash can be obtained with git rev-parse HEAD

The build script can

• write the current commit hash to a text file, or some kind of file like tres that can be packaged into the executables
• clean the build dir
• then build for all three platforms
• remove the commit hash file

Globals.gd will define a "version_info" dict which contains:

• hardcoded "dev" or "release" string
• hardcoded version number
• commit hash which is possibly loaded from text or tres file. hopefully this file ends up being part of the executable and can still be loaded from Globals.gd

The version string will be made as follows:

• If there is no commit hash (for example if we are launching from editor rather than something made with build script) then version is just version_number + "debug"
• If there is a commit hash and it's "dev" then it's version_number + "dev" + commit_hash
• If it's "release" then it's just version_number
