Addresses ([#140])
I don't think the zoom code in handle_key_events was necessary because
gui zooming already appears to be handled by egui::gui_zoom.
Description of keybindings:
https://github.com/emilk/egui/blob/59d71831fd43139bf9b427b779a241099b9c9826/crates/egui/src/gui_zoom.rs#L5-L26
Zooming using the described keybindings works fine with a textedit
focused.
This PR removes the ContextAction::SetPixelsPerPoint aggressively;
maybe it should remain for other future uses?
- allows use of more interesting args w/o risk of checking them in by mistake
- allows use of different args w/o rebuilding the app
- uses compiled in defaults if config file missing or broken
Example android-config.json:
```
{
"args": [
"--npub",
"npub1h50pnxqw9jg7dhr906fvy4mze2yzawf895jhnc3p7qmljdugm6gsrurqev",
"-c",
"contacts",
"-c",
"notifications"
]
}
```
Install/update android-config.json with:
```
adb push android-config.json /sdcard/Android/data/com.damus.app/files/android-config.json
```
Using internal storage would be better but it seems hard to get the config file onto
the device ...
