Worker: Improved flag handling, added error checks for config files,
minor fixes

Rewritten flag handling using GNUs getopt to prevent crashs in case the
arguments are shuffled or otherwise wrong.
Check first if files could be opened before working with them to prevent
crashs.
Removed misleading .rd0 comments and outputs since .rd0 files aren't
used by many people anymore. Replaced Rd0 variable names with Sim.
Scripts: Changed ordering of commands in wait loop when too many jobs are sent to blaster
Calib: Move fConvergenceFactor to base class TCCalib
Calib: Disentangle libCaLib from acqu_user libs
Calib: Addding fConvergenceFactor to energy gain calibration
User: Calib: Use photon energies directly, not the mean (variable names not changed though)
Calib: Use squared ratio of pi0 masses for energy calibration, according to Dominik's PhD thesis
Calib: Linear ratios converge better for uncalibrated gains

This reverts commit 3c3bdc2d5ecaf47bbbee8bd1796730277c5eb677.
Calib: Minor documentation fix
User: Calib: Quadratic energy correction might be broken anyhow, so use mean of photon energies

This reverts commit 1646cdcea36a5cadd03be3bb61c4db0ce9af8148.
