Conflicting allowBackup and supportsRtl attribute on manifest

[fthdgn]

The library AndroidManifest.xml contains android:allowBackup="true" and android:supportsRtl="true". These attributes create conflicts if the app which use this library has android:allowBackup="false" or android:supportsRtl="false".

I think this lines are not required for this library to work.

	Attribute application@allowBackup value=(false) from AndroidManifest.xml:6:9-36
	is also present at [com.sdsmdg.kd:trianglify:1.0.0] AndroidManifest.xml:11:9-35 value=(true).
	Suggestion: add 'tools:replace="android:allowBackup"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.

	Attribute application@supportsRtl value=(false) from AndroidManifest.xml:10:9-36
	is also present at [com.sdsmdg.kd:trianglify:1.0.0] AndroidManifest.xml:13:9-35 value=(true).
	Suggestion: add 'tools:replace="android:supportsRtl"' to <application> element at AndroidManifest.xml:5:5-19:19 to override.
