update of reference chapter completed

- Fixed bug #2866116 (Crash when creating functions with a large number of points).

- Update of alternative Czech translation by Jan Helebrant.

- Failed to understand the convoluted and demonstrably broken iteration logic in
Application::saveFolder(Folder*, const QString&). Replaced it by a simple
recursive method. Closes bug #2836125 (corrupted subfolders structure).

- Mark project as modified when moving folders.

- Applied patch by markc (quantumeer) fixing analysis operations on data where X
values are not monotonically increasing. Closes bug #2831634.

- Did some related code cleanup and fixed code duplication between
Filter::sortedCurveData() and Interpolation::sortedCurveData().

- Removed lots of unused files, which were either obsolete, redundant copies in
src/future or future code not yet being used. This should make it somewhat
easier for people to grasp the current code base.

- Changed defaults for linking to muParser on Linux. Contrary to what the
comment said, it definitely *is* possible to compile muParser 1.30 as a
shared library.

- Fix of two German terms in Czech translation, thanks to Pavel Fric.

- Removed changes which accidentally ended up in the last commit.

- Better Czech translation for the word decay in our context.
