* Adds methods for getting canvas size and character rendered size
* Changes the creation of frames to create them with the current size specified by the ASCIICanvas class
* Refactors the css:
	- Changes font size to be 1em
	- Changes line height to be more precise to avoid rendering additional pixel lines when there are errors in rounding the line height
	- Changes the canvas size to be 640x480 (it will be easier when we add some pictures to find and operate on that size, as it is standard 4:3)
Created a decent scroller
