[marvinvo]

Signed-off-by: Marvin Philipp Vogel [email protected]

Description

This PR gives the code generator plugin a new gui. The design is oriented to the recently changed TaskSelectionPage.

• Every question got it's own group and their answers are aligned vertically to reduce alignment lines.
• All text is wrapping so resizing won't lead to vertical scroll issues.
• "Note" boxes and it's content is grey so they distract less and within the questions group
• Add missing dispose call to fonts.
