Changed duplicated std fit ID to 6.
ParticleId: added Be10
ac_merge_simple: Fix memory leak when printing selectors.
Fixes compilation of ACsoft with AMSROOT support on Mac OS.

- C++11 does not work with AMSROOT
- Corrected the search paths for Xcode
Fixes performance bug in IO::FileManager::AssociatedAMSEvent().

- The check if a new file has startet compared the wrong strings.
- We have to call GetEvent() with the parameter kDoNotRewind=true to
  not loop over the chain again for each event.

Closes #1557
Remove workaround which produces tons of errors.
Add new step-by-step guide to doxygen.

Describe how to copy a new lookup file to AFS/CVMFS.
Include git version tag in version info file.
Prune old users/ directory, as done in acqt_600 branch.

The intention is to further minimize the diff between dev and acqt_600.
It is long discussed that ACanalysis is the repo to use for "user" software, not the users/ subfolder in ACsoft.
The code is still in the git history and not lost, if there is need to resurrect parts of it.
Give more particles predefined colors.
Add tools useful for plots:

 - function to include a string with information on how plot was
   generated (needs only one line of code per macro!)
 - function to generated a canvas divided into square pads while
   respecting the limits set for canvas size by the user (useful for
talks and papers)
 - work towards a generic style suitable for standard plots (large axis
   labels,...)

See the docs for details.
Work on scripts for 3D alignment.
Generalize tests of TRD tracking.

- write all particle species to minitree,
- add options to select specific species in test_trd_tracking and
  test_trd_tracking_minitree
- disable cut on full-span events for the time being
Add a few words about ACQt 5.9.3.
Changed particle colors to existing ones.
Fix return type for color.
Fix return type for color.
