Toolkit should use new orange #e95420

[Alan Bell]

this toolkit uses #dd4814 as the colour orange.

css/sass/constants.scss:26:$ubuntu_orange: #dd4814;
css/appTemplate.css:1033: background: #dd4814;
css/appTemplate.css:1168: background: #dd4814;
css/appTemplate.css:1440: color: #dd4814;

this has apparently been intentionally changed to #E95420 in the QML toolkit so this should probably be updated to match. Now I am really not sure if that should entail a version number bump from 0.1 to something else. There were previous discussions about symlinking a "current" pointer to a theme but these don't appear to have been implemented. As this is a fairly subtle change it is probably not going to break anything to update it in place without a version number bump.
