Start implementing slice selection
Merge branch 'v0.7' into v0.8

Conflicts:
	public/templates/cubeviz/DataselectionModule.phtml
Further implementation of the slices

- use slices instead of sliceKeys in the dialog to choose between,
because a slicekey does not allow to choose directly a slice (such as DSD)

- implement help dialog and translations
Remove title from icons in the left sidebar
Merge tag v0.7.1 into v0.8

Conflicts:
	public/javascript/Main-production.js
add element to slice dialog to have the option to select no slices at all

Otherwise, if at least one slice exists, you have to select one of them
Update selectedSlice entry after choose a new one
Enrich assets/cubeWithMaterializedSlices.ttl with one more slice

And fix base uri
Fix URI's in assets/cubeWithMaterializedSlices.ttl
Fix wrong attribute/measure relations in assets/cubeWithMaterializedSlices.ttl
Make slice selection fully runable (could by fragile sometimes)
Analyze section to inform user about the selected DataCube / knowledgebase
Add mockup for overview
Replace parts of the mockup with real values and extend mockup with dataset fields
Fill all elements of the mockup with life!

Now you have the possiblility to get information about:
- dsd
- ds
- slices
- attribute
- measure
- dimensions and their associated information
Add number of used and valid observations
Update font-awesome to version 3.1.1
Add a couple of unused observations to assets/cubeWithMaterializedSlices.ttl
Add possibility to get a notification if knowledge base contains unused observations
Use menu entry instead of extra module in left sidebar for opening analyze-area
