Migrate to Capacitor

[HarelM]

Infra

Cordova maintenance (both plugins and core libraries) is far from ideal.
Issues there are open for a long time without reply, pull request are not picked up. It's a very bad sign and it seems like the community is migrating to Capacitor.

As a result, I believe now is the time to migrate too.
It will not be simple, it will cause a lot of noise but I hope that in the end, we will be in a far better place.
The main benefit, but also the drawback, is that you get to maintain the code that is specific to the platform and be able to change it without waiting for a PR to land or a version to be released.
I'll start this on a branch and see how it goes.
It's probably better to release a version before starting this just to be sure the latest code is not waiting to be released...

A possibility for an initial version in Capacitor might be by using Fiverr services.

Fiverr leads died out unfortunately.
I've tried to migrate using all the plugins and it failed in iOS with compilation error I was unable to resolve (didn't try too much though).

So I've decided to go the other way around - i.e. remove all the plugins, set compilation flag to not cordova (i.e. same as website) and it worked, now there's a need to add back all the plugins.
I'll try to use the cordova plugins first. If this fails I'll see if I can replace some with capacitor plugins.

Tasks:

• Fix icon stuff...
• Update CI
• cordova-plugin-purchase - offline subscription
• cordova-sqlite-ext - offline maps (later on maybe: https://github.com/capacitor-community/sqlite)
• cordova-plugin-file - https://capacitorjs.com/docs/apis/filesystem - also there's this issue with FileReader
• cordova-plugin-file-transfer - download large files - no replacement?
• cordova-plugin-zip - unzip in native - not in use
• cordova-plugin-x-socialsharing - share files, e-mail, etc
• cordova-background-geolocation-plugin
• cordova-plugin-device - device info - @capacitor/device
• cordova-plugin-camera - @capacitor/camera
• cordova-plugin-deeplinks - @capacitor/app
• cordova-plugin-brightness - brightness and keep screen on - @capacitor-community/keep-awake,
• back button
• deep links
• cordova-plugin-device-orientation - orientation
• cordova-plugin-media - playback - @capacitor-community/native-audio
• cordova-plugin-network-information - ? not in use
• cordova-plugin-oauth - login
• cordova-plugin-screen-orientation - ? not in use
• cordova-plugin-statusbar - a status bar bug fix in iOS - I decided to simply hide it, we'll need to see how this is accepted by the users...
• cordova-plugin-vibration - needed for iOS as it doesn't support the browser native API
• es6-promise-plugin - ? not needed I think
• phonegap-plugin-mobile-accessibility - usePreferredTextZoom - keep font size untouched - replaced with @capacitor/text-zoom
• replace all isCordova with isCapacitor
• replace pause, resume, resign
• Fix TODOs
• Think about migrating old databases or at least clear the database update time when upgrading...
• Change minor version? Major version?
• Check to see that iOS data is stored on upgrade (not just offline database)
• Replace UntypedFormControl
