Remove android:label from the Manifest

[SpaceBison]

Setting label in the library manifest causes conflicts and errors such as this:

Error:Execution failed for task ':cityfit-kiosk:processDebugManifest'. Manifest merger failed : Attribute application@label value=(@string/common_app_name) from AndroidManifest.xml:14:9-48 is also present at [com.p_v:flexiblecalendar:1.2.1] AndroidManifest.xml:13:9-41 value=(@string/app_name). Suggestion: add 'tools:replace="android:label"' to element at AndroidManifest.xml:10:5-74:19 to override.
