Merge remote-tracking branch 'origin/DeadStrawLookup' into dev

First attempt at ACROOT removal.

- Removal of ACROOT functionality from FileManager.
- Removal of all ReducedEvent-related things in Particle and ParticleFactory.
- Removal of all ACROOT-dependent code from TrdQt and Cuts.

This breaks template_posfrac (relies on self-produced minitrees) and reduce_event_tree (ReducedFileHeader no longer available from FileManager).

Also renders analysis_template obsolete, which showed how to use ACROOT files.

refs #1359
Removed unused support for CustomVariables from template_posfrac program.
Remove program for writing obsolete custom tree for template_posfrac program.
