Fixups, Implement a Run btn, and add some weapons/armor tweaks

[adelikat]

1. Refixes the drag and drop functionality that was removed in a bad merge

2. Fixes compile errors (there label click events that pointed to functions that didn't exist, wasn't sure if there should be events or not but those aren't typical, so I figured someone attempted to remove unused events and a bad merge put the references back in the designer file.

3. Adds a Run button that enables after you click Randomize. If the user hasn't registered .nes files with an emulator it will open a dialog to pick the application. Once set up, this is a super handy way to create a new seed and open it

4. I added what I think are some balancing weapon/armor tweaks, pre-randomization. I made them a separate function so they can easily removed if others don't agree.
   Summary of these tweaks:

• Increase power of Staff of Reflection to make it the best weapon for wizards and worth the incredibly find
• Increase power of orochi sword so that it is a harder decision between it and zombie slasher for sages (zombie slasher is 5 less now, but overall better in most situations due to undead bonus)
• Allow merchants to equip Shield of Strength (otherwise they get really useless in the endgame)
• Dragon Mail for sages, Gives them something better than pilgrams and an added incentive for the class change

Also, the tweaks start a concept of "improving DW3" and then randomizing the improved version. It's my favorite game but there's definitely some imbalances in it and overall a lot of the weapons aren't useful. There are lots of other potential improvements that could be done in the future
