Stop using git for the version tag.
The new process is as follows:
1. The `VERSION` file contains the version.
For release, it should contain "1.5.0".
Immediately after the release, it should be changed to "1.6.0-dev".
2. The build type is included in the version string unless it is
"Release". The commit hash is now included into the version string
whenever the `VERSION` file has a suffix (i.e. 1.5.0-dev rather than
just 1.5.0). The full version string for development builds now
looks like this: `1.5.0-dev-Debug-b102dccf8`.
This means we longer need git or `-DVERSION_NUM` to get a sensible version number.
The in-development versions are now always clearly indicated with the
`-dev` suffix no matter how DevilutionX was built.
If a config directory did not exist, the ini file was
not saved at all.
Only implemented for targets that support `std::filesystem` or `std::experimental::filesystem`.
These are all the targets except nxdk and iOS (only supported on iOS 13+).
1. Make the vcpkg hack minimal by only defining the options it needs
before `include(Platforms)`.
Every dependent option needed by vcpkg has to be recalculated
after `include(Platforms)`. This brings the count of such options
down to 1 (`PACKET_ENCRYPTION`).
2. `include(Platforms)` before the rest of the options.
3. Group related options together into sections and add comments.
4. Fix `--gc-sections` for C files. Also adds `-Wl,--as-needed`.
Note: `PIE` can now be `ON` even if `BUILD_TESTING` is `OFF`.
1. Platform and toolchain files are now all under `platforms/`, with a
single `CMake/platforms/${platform}.cmake` per platform.
2. Custom functions/macros are under `functions/`.
3. Finder modules are in `/finders`.
