Package name issues

[noahjutz]

Current package names are:

• com.noahjutz.splitfit.fdroid for F-Droid build flavor
• com.noahjutz.splitfit.googleplay for Google Play build flavor
• com.noahjutz.splitfit is currently published on google play.

In order to avoid confusiong among users that use both stores, remove the suffix (.fdroid/.googleplay).

Removing .googleplay should be easy.

Removing .fdroid might require some changes in fdroiddata because com.noahjutz.splitfit.fdroid is already published on F-Droid.

Replacing this will most likely be version name suffixes.

Maybe my request #41 will be affected by this issue too

Renaming the app doesn't require renaming the application id/package name, but it would be a good opportunity to do it while solving this (#38) issue
