Add ASCIIMatrix class for abstract operations with matrix
Tested obtaining parameters from links through jQuery and accessing other elements
Merge branch 'master' of https://github.com/deyan-hadzhiev/ascii_player
* Changes ASCIICanvas to actually use the ASCIIMatrix class.

* Added clear and init methods to the ASCIIMatrix for initialization.
* Adds the copy constructor of the matrix class
* Adds methods for getting width and height to the matrix class
Frame manager
Using Frame Manager instead of Canvas
Working playPause and addFrame buttons
Sync with master
Fixed matrix getHeight/Width. Calculated good dimensions for canvas size
Sync with master
* 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)
