Markdown and learning progress features are no longer considered
experimental. Leaning progress can no longer be globally disabled.

Added 'ui' prefix for splash screen settings.

Feedback reset will be disabled for liveClicker-sessions.

An LDAP search pattern can now be used instead of binding with a DN
pattern.

This reverts commit fc78eb18.

SASS variables only exist at compile time and are not available for
arsnova.properties.

The default exception handles all excaptions not handled by the
following handle methods.

It creates a response, containing the HTTP status description
and the exception message.
This response can be serialized into JSON.

It generally might not occure but in some conditions the previous code
could be used to inject something into response by manipulating the
origin header to include some \n or \r.
These sequences should not occure in results CORS headers.

Patch replaces all \n or \r in origin header with a white space char.
Newer servlet containers like Tomcat 7.x fix this problem, but it might
be a good idea to fix this issue within ARSnova.

NovaEvents is derived from ApplicationEvent which extends EventObject.
EventObject implements Serializable.

It is bad practice if defined instance fields within NovaEvents
derived classes do not implement Serializable.

A boxed primitive is created from a String in
* RangeAspect#handlePaginationRange()
* LoginController#dialog()
just to extract the unboxed primitive value with Integer#valueOf().
This creates an Integer object. It is more efficient to use parseInt()
which creates a primitive int.

Corrected random indention in LoginController

In getSkillQuestion() a call to stubQuestions.get() contained an argument
with an incompatible class. Session will be converted into String using
toString() but this is not what was intended to do here.

In saveQuestion() the CouchDB document ID was used, but the sessions
keyword should have been used instead.

User object will be serialized into a String using toString() but this
should not be done in a unit test.

remove swagger annotation from feedbackcontroller, coursecontroller and getter and setter for sortOrder

remove spingfox for ApiIgnore direction
use swagger-maven-plugin to generate swagger.json before compiling rather than
 dynamically generate it on request

Reasons:
* not used consistently
* Java signatures are not helpful
* Return type should not be hard-coded in a String

Statistics model now correctly uses value instead of notes for
documentation of properties.
