cellspace updated with post jam version

So i had some time to work on the post jam version and did some improvements and i kind of like this project. I am consider to doing a proper full version of this in the future when i get more time. 

For now, you guys can enjoy the post jam version with a lot of updates.

Some of the changes are:

•  AoE cell added, the square damaged everything around it after a initial charging time
•  Healer cell added, heals cells around it
• Cell rewards now adds instantly once instead of being added to the spawn timer
• Graphical update, now the graphics should be more crisp since i took the liberty to actually use some decent sprites instead of Unitys default ones
• Audio improvements
• Balance changes
• Bosses now have more distinct abilities
• Cells can now only spawn a distance from the base
• UI improvements, now the canvas scales with screen
• Visual indicator updated with a arrow

Let me know what you guys think of the game in its current state :)
