OBT v1.0.3 - core mode, clear data, weapon balance

You know, I decided to play a little the game last night, and I was playing the game for a while last night, and before I knew it, I was on level 22, with a score of 2312. Then I thought: this is too easy. I need to re-balance it.

The shotgun is just too powerful with 50 shots (Really, this is the weapon that I used the most during my run). So I reduced it to 40. I think I'm more satisfied with how it is now... though I may re-balance weapons again sometime, who knows?

Still, I get to level 20 too easy in this game now, so I created a "new" mode. The CORE MODE contains the game as it was before version 1.0.x, that is, no pickups to get a different weapon. Just the turret with the default weapon surrounded by dozens of enemies. Just the way we all love, right?

Also, now there is the option to clear the highscores on the settings menu.

Well, that's it for this update. Hope you like it!

I'm open to suggestion of things you would like to see on the game.
