Worklog #3

Alright, the Building Editor and Upgrade Editor now work.
I am going to be making the buildings and upgrades for Island Defense later today.

Also, upgrades will be used through scripting through scripting such as
setProperty(Health, getProperty(Health) + 100);

for a stat upgrade.

You now use a combobox to select upgrades for units now.
Mana property has been added.
