Feature tawkie identity

[VincePaulin]

The iOS and MacOS part remains to be done as soon as I can.

I can add further modifications if necessary

$ grep -r  im.tawkie    
scripts/build-macos.sh:FLUFFYCHAT_ORIG_GROUP="im.tawkie"
scripts/build-ios.sh:FLUFFYCHAT_ORIG_GROUP="im.tawkie"
macos/Runner/Configs/AppInfo.xcconfig:PRODUCT_BUNDLE_IDENTIFIER = im.tawkie.tawkie
ios/Tawkie Share/Tawkie Share.entitlements:		<string>group.im.tawkie.app</string>
ios/Runner/Info.plist:			<string>im.tawkie.app</string>
ios/Runner/Info.plist:				<string>im.tawkie.app.uris</string>
ios/Runner/Info.plist:					<string>im.tawkie</string>

ios/fastlane/Appfile:app_identifier("im.tawkie.app") # The bundle identifier of your app
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = im.tawkie.app;
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = im.tawkie.app;
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = im.tawkie.app;
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = "im.tawkie.app.Tawkie-Share";
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = "im.tawkie.app.Tawkie-Share";
ios/Runner.xcodeproj/project.pbxproj:				PRODUCT_BUNDLE_IDENTIFIER = "im.tawkie.app.Tawkie-Share";
android/app/src/main/AndroidManifest.xml:                    android:scheme="im.tawkie" />
android/app/src/main/AndroidManifest.xml:                    android:scheme="im.tawkie" />

I think these should be fr.tawkie instead of im.tawkie. The im is just the TLD used by Fluffychat's Domain Name
