Various changes

Browse Source 
- added `/:paletteSlug/:resolution` functionality for localhost testing
	- created `currFile.sublayers` for *things that should zoom with the canvas layers*
	- `currFile.layers` now solely contains the canvas layers
	- added `getProjectData` to `FileManager`'s exported methods
	---
	- added `FileManager.localStorageSave` (it's basically just: localStorage.setItem("lpe-cache",FileManager.getProjectData()))
	- added `FileManager.localStorageCheck` (it's basically just: `!!localStorage.getItem("lpe-cache")`)
	- added `FileManager.localStorageLoad` (it's basically just: `return localStorage.getItem("lpe-cache")`)
	- added `FileManager.localStorageReset` (for debugging purity)
	---
	- calling `FileManager.localStorageSave()` on mouse up (we should stress test this)
	---
	- changed lpe file format to `{canvasWidth:number,canvasHeight:number,selectedLayer:number,colors:[],layers:[]}`
	- added backward compatibility for the old lpe file format
	---
	- added some canvas utility functions in `canvas_util`
	- added Unsettled's color similarity utility functions in `color_util2`
	---
	- html boilerplate - wang tiles
	-
	- POC - tiny text boilerplate
	- POC - tiny text font scraper
	---
	- WIP - added two optional url route parameters `/:paletteSlug/:resolution/:prefillWidth/:prefillBinaryStr`
	- WIP POC - hbs_parser.js (outputs tree data about hbs file relationships)
