Upgrading pre 1.12 Android project to v2

[k5924]

Problem: Error message would appear when building the application asking stating that the app is using a deprecated version of Android embedding

List of Changes: In AndroidManifest.xml

• Changed reference to Flutter Application in application tag to ${applicationName} In app/build.gradle:
• Update minSdkVersion and compiledSdkVersion to avoid error messages caused by updating the kotlin version due to an error limit exceeded error In android/build.gradle:
• Update kotlin version to latest version
• Update com.android.tools.build:gradle to 4.2.0 In gradle-wrapper.properties:
• Updated the distributionUrl to point to gradle-6.7.1-bin.zip

Note: Due to the code editor I am using, the code in AndroidManifest.xml was given a different formatting style but the application appears to operate as intended This solves #43

Thanks alot @k5924 👏

I've resolved conflicts and done some cleanup (unecessary .project & .settings/* files) I'll merge soon.

I also reverted some gradle version changes : why did you downgrade them?

Thanks :)
