Change of license

[tilladams]

We must get forward changing the license from GPL especially for the server-side stuff.

Me and @marcjansen suggest to move to 3-Clause BSD-License ("Revised BSD License", "New BSD License", or "Modified BSD License", see wikipedia, and opensource.org) as it it quite simple.

Steps to be done:

• every committer has to agree, that his/her code is switched to above license
• change of license header in the code

For the client all code must fall under the ExtJS license conditions.

For the future I'd prefer to divide SHOGun in SHOGun Server (3-clause BSD) and SHOGun Client (follow ExtJS License) in general and perhaps a switch away from ExtJS.

Steps for completion:

• Agreement of past contributors (according to https://github.com/terrestris/shogun/graphs/contributors):
  • @marcjansen
  • @chrismayer
  • @weskamm
  • @buehner
• Actually changing the license in the codebase, see Relicense SHOGun to BSD-3-clause #57
• Additionally we should make it even more explicit that for client code using ExtJS, Senchas licensing options apply (http://www.sencha.com/products/extjs/licensing), see Relicense SHOGun to BSD-3-clause #57

The Sencha document Exception for Development Version 1.04, January 18, 2013 hints that the 3-Clause BSD-License ("Revised BSD License", "New BSD License", or "Modified BSD License", see wikipedia, and opensource.org) is actually approved by Sencha.

I hereby agree that my submissions to SHOGun are relicensed to 3-clause BSD.

I suggest the following headers:

JavaScript-code (also CSS etc.):

As above, but with an additional paragraph:

/* [...]
 * 
 * The client-side code of SHOGun partly depends on the ExtJS-framework (see
 * http://www.sencha.com/products/extjs, available separately under various
 * licensing options: http://www.sencha.com/products/extjs/licensing); it is

 * open-source-license-exception-for-development/).
