change or listing changes.

- Minor specfile cleanups.

- Update to version 2.2.6:
* Add initial-state p_z and inelasticity selectors for DIS (#80)
* Improve the reweighting to include the local K=BBar/B factor
in MEPS@NLO runs (#73)
* Improve treatment of the shower reweighting scale cut-off, it
is now applied also when reweighting AlphaS and the PDFs in
the CKKW clustering sequence (also mentioned in #73)
* Adapt status=4 convention in the short HepMC output (#79)
* Compute approximate NLO EW corrections (and subleading orders)
as on-the-fly alternative event weights (#41). See Example in
Manual for details. Currently only works with a
soon-to-be-released version of OpenLoops.
* Add a filter between the perturbative and the non-perturbative
event phase, which can be used to reject events with
parton-level cuts (!94)
* Bug fixes:
- Fix NLO and Variable Selector routines (#70, #88)
- Fix unweighting treatment for the LocalKFactor (and its
on-the-fly variations) in negative events (#94)
- Fix argument validation in
GGH_KFactor_Setter::ClusterMassCorrectionFactor
- Fix core scale setter for DIS when the incoming particles
are ordered ep instead of pe and adapt it for ee->xy (where
xy is not a quark pair) (!81)
- Fix strong coupling reweighting in merging runs in cases
