Migrate to AndroidX

[guger]

As the AndroidX version of AppCompat is stable now, I'd recommend to update.

It's as simple as changing the imports in the files.

import io.multimoon.colorful.BaseTheme
import io.multimoon.colorful.CThemeInterface
import android.os.Bundle
import androidx.appcompat.app.AppCompatActivity

open class ThemedActivity : AppCompatActivity(), CThemeInterface {
	
	override var themeString: String = ""
	
	override fun onCreate(savedInstanceState: Bundle?) {
		super.onCreate(savedInstanceState)
		handleOnCreate(this, savedInstanceState, BaseTheme.THEME_APPCOMPAT)
	}
	
	override fun onResume() {
		super.onResume()
		handleOnResume(this)
	}
}
