added clion run configs

previous behaviour: all platforms would compile both infer and xdg-mime
new behaviour: unix platforms always compile xdg-mime but only compile infer if the `infer-backend` feature is enabled, and windows always compiles infer but only compiles xdg-mime if the `xdg-mime-backend` feature is enabled.

 ```bash
+git clone https://gitlab.com/Lynnesbian/fif/
+cd fif
+# run tests (optional)
+cargo test --locked
+# build fif with its default feature set
+cargo build --locked --release
+```
+The `--locked` flag ensures that Cargo uses the dependency versions specified in [the lock
+file](https://gitlab.com/Lynnesbian/fif/-/blob/master/Cargo.lock), and the `--release` flag builds fif with release
+optimisations enabled -- this takes longer, but produces a much faster binary.
+
+### Installing
+```bash
+# install the fif crate (to ~/.cargo/bin or %USERPROFILE%\.cargo\bin by default)
 cargo install --locked fif
 ```

+fif supports using [`infer`] or [`xdg-mime`] as its backend for looking up file types. By default, xdg-mime will be
+used on [*nix systems](https://en.wikipedia.org/wiki/Unix-like) (Linux, macOS, *BSD, etc.), and infer on all other

+`xdg-mime` should work on any *nix system with the [Shared MIME Info] library installed (consult your package
+manager), although I've only tested it on Linux and FreeBSD. `infer` should work on any system.
 
 You can override the default backend for your system at compile time like so:
 
 ```bash
 # xdg-mime
-cargo install fif --features=xdg-mime-backend
+cargo install fif --locked --features=xdg-mime-backend
 # infer
-cargo install fif --features=infer-backend
+cargo install fif --locked --features=infer-backend
 ```
 
-Of the supported backends, `xdg-mime` by far supports the most file types, as it uses the excellent [Shared MIME
-Info](https://gitlab.freedesktop.org/xdg/shared-mime-info/) database, whereas `infer` uses its own baked-in database.
-However, `infer` is also faster to load, if only by a few dozen milliseconds, and has no external dependencies.
-
-#### Multithreading
-It is also possible to disable multithreading by installing without default features:
+It is also possible to get a more minimal build by installing without default features:
 ```bash
-cargo install fif --no-default-features
+cargo install fif --locked --no-default-features
 ```
+This will disable some non-essential but nice to have features, like multi-threading support.
+
+For more info on fif's compile-time features, see [the wiki](https://gitlab.com/Lynnesbian/fif/-/wikis/Cargo-Features).
