Refactored Predefined Goal Form Submits

Many of the predefined goals had duplicate code in their submit buttons,
so it's now all in one, "SaveGoalToList" method.
Second predefined goal form refactor

Took too much into the method the first time. Now the save to list
method only saves, and doesn't also finish the activity.
Changed enum namespaces

While trying to fix a different bug, I corrected the enums' namespaces,
which updated several classes.
Monster enums

Added the enums for the monster mode display.
Monster enum - food

Missed one in the last commit.
Rank stored in preferences

The user's rank is now stored in the shared preferences, to be accessed
from anywhere.
Monster mode set up

Can display monster mode progression and assign monster types and
weapons, etc. when a goal is created.
