Bug Fixes for Elements

• A bug was fixed in RFCA and RFCW elements related to edge focusing with N_KICKS$>$1. In addition, N_KICKS now defaults to 0, since this gives better results in most cases. This was reported by M. Cornacchia (SLAC).
• A bug was fixed in the matrix for the RFDF element. It didn't reflect the setting of the STANDING_WAVE parameter, but behaved as if STANDING_WAVE=1. This would only affect twiss parameter calculations, matrix output, etc., and not tracking.
• A bug was fixed for the CSRCSBEND element, which affected the $x^\prime$ coordinate in the
  PARTICLE_OUTPUT_FILE. Instead of $x^\prime$, the code was providing $q_x = x^\prime (1 + x/\rho)$. This would not affect any other results.
• A memory leak was fixed for the KQUSE element that would affect long-running simulations. This was reported by V. Sajaev (ANL).
• Synchrotron radiation is now turned off for multipoles less than 1$\mu$m long, to avoid ridiculous results. This is not really a bug.
• WATCH elements were providing incorrect charge information when particles were lost. This has been fixed. (Y. Wang, ANL.)
