If SVG width and height are not define, set them to 100%

Fix deprecation warnings

rawgit.com is going down, use github directly

should fix #56. This should also have the side effect, that the SSL
setup is a little more relaxed (more compatible certificate upstream)

Enable loading local icons in sidebar nav

denied, even if they are not ACL protected

Fixes #19

Update CDN URL for SVG icons

fix caching for SVG files

we do not need a session to be initialized for the SVG requests.

Fix svg replacement in Greebo+

The surrounding underscores can be left out.

Now the SVGs are loaded via AJAX and are directly embedded into the
HTML. This allows for styling them via CSS and we can apply proper hover

The svg dispatcher was extended with an embed option (boolean parameter
'e') which will return an absolute minimum svg with absolutely no

first go at a dispatcher to dynamically recolor SVGs

The script accepts the following parameters:

svg - the SVG to load. Either an image in the img directory next to the
script or a media file id. ACLs are checked
f - wanted fill color
s - wanted stroke color
fh - wanted fill color on hover
sh - wanted stroke color on hover

Colors are to be given in hex in the following formats:

RGB
RRGGBB
RRGGBBAA

What's missing:

* being able to define what is styled, currently hardcoded to 'path'
elements only
* caching - no need to do all the processing every time
* background setting - that would require wrapping an additional <g>
or <rect> element around all content and style. I'm not sure how to do
that best.
* unit tests
