update1.04 for TowerRogueBuilder

I have made it possible to save the progress.

a little bit of new features to experiment what will feel good for the game before it fully released (2.0 will be the full release hopefully)

i'm planing to add more to the game a lot more till i make it a playable enjoying experience

but i hope someone will give me a feed back to help out guide me to do right stuff 

Right now i have this ideas in mind : -shop for upgrades -monsters will have increasing difficulty and special traits with hopefully attack animation soon :) - more towers to place hopefully with intresting mechanics -more cards to draw from in the roguelike aspect.
