This reverts commit 448b804dc642b977474e2ef5f5ce438187fd56e1.
Add new testcase for colorbar

R2014b handles colorbars smart:  `XLabel` and `YLabel` merged into `Label`
Use colormap 'jet' to create comparable output with MATLAB R2014b
* Check horizontal/vertical colorbar (subplots)
* Check if 'direction' is respected
* Check if multiline label and title works
* Check if latex interpreter works in label and title
add function `isHG2` that returns graphic system
fix multiline colorbar title
Handle colorbar differently in HG2 graphics system

MATLAB R2014b introduced an new graphics system. It is object oriented and changed some behavior. For example colorbars are now not treated as axes objects any longer.

For exmpale, now there is only one 'label' for the whole colorbar and one 'direction' setting.
add TODOs
use old syntax
String comparison with `strcmpi`
Merge branch 'fixStrcmpi'
Parallel make for ACID test
Clean ACID test output before running

This can be toggled using the `cleanBefore` flag.
Internally, `make clean` is used to do so.
This has the downside that on any system without a make
on the path (most installs of Windows), this does not work.
However, this downside is mitigated by the `try-catch`, such that
on improperly set-up systems, this doesn't break execution of the tests.
Merge branch 'parallelTests'

Tested on R2014a, R2014b

Test 87 might cause troubles in R2014b, since the output is completely
empty there. Ideally, this should be #384 as this covers annotations in R2014b.
