Includes changes fromp v490-alpha.4, v490-alpha.5, v490-alpha.6

Eventdisplay v490 is a major update of the reconstruction and analysis code used for VERITAS.
This update includes significant changes which break the analysis of older versions at certain stages.

Running this version requires also updates to the newest versions of Eventdisplay_AnalysisScripts_VTS and Eventdisplay_AnalysisFiles_VTS (private repository).

This is a pre-release with substantial changes expected in near future. Please try it out, but don't use it for science publications.
Changes with relation to v490-alpha.3 are:

Use Pointing status bit

VPM report success of pointing reconstruction. This is used now, events without useful pointing are discarded (generally very few events; often at the very end of a run)

Improvements in plotting of instrument response functions

Re-enable plotting of instrument response functions vs true energy: Effective area files contain since v497 two trees: fEffArea (with reconstructed energy axis) and fEffAreaH2F (with true energy axis). Change reading routines to re-enable plotting of IRFs vs true energy.

Improve angular resolution plotting and fix issue with plotting cumulative theta2 distributions.

Energy axes for energy reconstruction lookup tables

Removed dynamic setting of energy axes limits (1D histogram for tables) in lookup table code and fixed it to 150 TeV (well beyond what we do in VERITAS). Dynamic settings were introduced for CTA (telescope types), but the version in Eventdisplay_v4 had a minor bug.

DISP reconstruction

Improvement how head/tail uncertainty is resolved. Apply minimum angle cut for 2-tel events only.

Remove duplication of date/MJD in season definition

Having both MJD and SQL-strings lead to errors in definitions of yearly seasons. Removed the MJD, which is now calculated in VEvndispRunParameter from the sql string.

Remove obsolete TableEnergy filling

Remove filling of unused tables with energy / R axes

Unweighted simulated histograms

Add unweighted histograms to effective area output files (mostly for debugging now; later useful for DL2).

Command line parameters to overwrite target runinfo DB values

Add possibility to overwrite the DB settings for target information (read usually from the runinfo db table): -overwritedb_rightascension, -overwritedb_declination, -overwritedb_target (this complements the existing command line options for the wobble offset: overwritedb_wobblenorth and overwritedb_wobbleeast
