Over two months behind schedule, Metatanks is finally complete

Changelong:

Gameplay Additions:
-Changed a lot of graphics. A lot.
--The player and all enemies have been redrawn from scratch.
--Made shell projectiles darker and more vibrant, to hopefully better stand out from the background.
--Smoothed out some explosion sprites, since now they looked rough in comparison to the new sprites.
-Shielded Pods now give off particles while they are chasing the player.
-Added two new stage themes, for episodes 1 and 2.
-There are now warnings for mortar shots, the Metatank's flamethrower, and certain Metatank attacks under certain circumstances

Gameplay Changes:

-Slightly decreased the range Plasma Tanks will search for paths to shoot their target, decreasing the odds they start aiming behind them counterintuitively.
-Changed the location of Metatank projectile spawning for some attacks, due to art style change changing where the barrels for the Metatank's guns are located.
-Changed the Charger's hitbox
-Changed some details of the Metatank's weapons, mostly to compinsate for the artstyle change.

Bugfixes:
-Fixed crash caused by dying to a Metatank's laser gun. How did I miss that one?
-Fixed glitch that caused the game to crash if you were destroyed within a few frames when starting a new level.
-Removed Metatank's third phase from being able to have Sheilder Pods Orbit it, hopefully fixing a strange, rare crash.
-Fixed glitch where Metatanks would gradually eat up audio channels due to impropperly dealing with the enemies it uses to decide it's weapon loadout, resaulting in sounds eventually randomly cutting out if too many Metatanks spawn.

Other:
-Changed the compile settings on the Episode_1 theme, hopefully removing the same weird ringing that was in the final boss theme.
-Fixed an inconsistency in the creator names
-Reworked how the game loads levels for user play to make the game more user-friendly.
-Improved level select screen, allowing for user-made levels to appear on it
-Improved some background code of the sound system and music system during the fixing of the Metatank sound glitch, which should further decrease the ammount it glitches out.
-Added effects for buttons being selected and clicked, including implimenting some clicking sound effects I had apparantly already made and forgot to impliment.
-Added a new menu theme
-changed to compile settings on the final boss theme, fopefully removing that weird ringing during the high-pitched sounds.
