[#2537] indicate selected ability when targeting

[weiquu]

This fixes issue #2537

My wallet address is 0x848fBf0588B448f14a2a8BA84Ef12711677073Db

Outline of solution:

• Added the svgs for unit abilities to Phaser assets so that they can be used for sprite textures
• Add 'ability' to the hovered hex's overlay visual state, remove it on click (ability used) and hover off
• If 'ability' is in the overlay classes and there is an ability selected, add the appropriate abilityIcon; else, set alpha to 0
• Frame and background are set in the hex's constructor, with alpha toggled along with the the abilityIcon
• abilityIcon brought to top of overlay group each time it's displayed so the icon can be seen more clearly

@weiquu Heya! Um, no resizing of icons please; use other ways for spacing out stuff, like adding extra divs and using code.

Hey @DreadKnight, I meant scaling the sprites down, not actually changing the .svg files. Is that fine? I did something similar here as well

Doing it through code like that should be ok. I get that this is a draft, just wanted to make sure of this approach aspect.

@DreadKnight ready for review!

@weiquu Only did some testing with Firefox, 2 stacked Dark Priests for each player, mouse wheel working badly and no showcased ability icons at all. Will test soon with Brave as well. Also, I understand that icons need to be moved into the autoload folder, but UI should use them from there, it's important to avoid duplicated, but you've changed the icons I think.

@weiquu You can test it here btw -> https://ancientbeast-9pgv468k0-freezingmoon.vercel.app
There's also web based IDE like VSC.
