License clarification: HTML,CSS,images,fonts under permissive licenses.

Clarify in LICENSE.txt that the noVNC core library is the part that is
LGPLv3 licensed. The HTML, CSS, images and fonts are separate from the
core library and can be modified and distributed with the noVNC core
but under their own license conditions.

HTML and CSS: 2-Clause BSD
Fonts: SIL OFL 1.1
Images: CC BY SA 3.0

In other words, you can modify the layout and appearance of of noVNC
to integrate with an existing or new web site or application without
having to publish the source for those modifications under the LGPLv3.
However, use of and modification of the noVNC core library (i.e. the
core Javascript that makes up noVNC) must still be according to the
LGPLv3.

Chris Gordon was the other contributor to the HTML, CSS, and images
included with noVNC and gave permission for this license clarification
on June 23, 2012.
