Temp branch for merge

[Bluntsord]

Added a buildUI, Item class and tower Inventory class.

build UI has var tower_to_be_built that changes upon clicking of the buttons in the build tool. Also can toggle between build mode and inspector mode.(Not needed feature as of now)

item class just has a texture rect that has attributes.
Items have 4 attributes as of now:

1. Damage
2. Attack Speed
3. Projectile Speed
4. Range Increase

Lastly the towerInventory class is composed by the tower class. Each tower has a tower inventory. Upon opening it, it gives a visual representation of the items equipped and the stats of the tower.

Currently the buildUI and the towerInventory is not under any folder but will both go under the UI folder when completed.

Hey i see a lot of *.import files were deleted. Could you reopen the godot project (that should trigger .import file creation), git add assets/img/ then commit and push? *.import files are necessary for source control, .import directories must be gitignored (src)

When you push on the TempBranchForMerge, you don't need to worry, it will auto update this PR.

From our discussions:

• Move all game/.tscn and game/.gd to their right places
• Move tower selector to UI, take it out of tower.tscn and keep it as part of UI elements
• Set UI buttons to trigger set_action(...) when pressed by user
• Have tower inspector have a variable called tower that will be set by map, and remember to reset it to null when user clicks another button (closing the inspector)

Meanwhile I will work on:

• game ground tile assets
• making sure aspect ratios from 4:3 to 21:9 are supported with filler tilemaps, with the real base aspect ratio always being 16:9.

hmm we didn't discuss why Tower should be a KinematicBody, could you explain here?

Will manually merge and ask tc to use a separate branch to stop making more unrelated commits to this PR.
