Oreon-System-Manager/CHANGELOG.md

## 8/12/24

Commit 1
- Removed `on_shutdown` function from `src/main.rs`, as it was uselessly dropping memory that was automatically dropped right after the function ended.
- Finished the documentation for `src/main.rs`, `src/packages/installed.rs`, `src/packages/browse.rs`, and `src/packages/mod.rs`
- Renamed `show_installed_package` to `show_package`, and merged it into `src/packages/mod.rs` instead of having copies in two files.
- Added this changelog.
- Updated `inst.sh` so that it no longer copies `style.css` to the `/usr/share/oreon-system-manager` directory.

Commit 2
- Moved `drivers` to it's own module folder
- Added `src/drivers/mod.rs` and `src/drivers/objects.rs`

Commit 3
- Fixed crash on package description fetch
