Tooltip and File Reading Proofs of Concept

Very basic tooltip implementation
- Popup message when the cursor is idle (stationary) for a period of
time
- Intended to provide helpful information, labels to icons etc.
- Currently entirely for proof of concept

Proof of Concept for reading text files and parsing text
- Can have application launch into CombatMap by changing
configuration.txt
- User settings will be saved in text file for subsequent executions of
the application
- Can extend file reading to implement save/load feature, store object
data for items, abilities, modifiers, etc. outside of the code

The code handling new and expiring error messages should be slightly
more efficient.
