Adding a pt3 member to L1TJetsMatching class, for HLT development

[albertdow]

This change adds a new member to the L1TJetsMatching class (pt3Min_) that allows one to use the L1TJetsMatching module and it's 'ThreeJets' output collection when pt1Min = pt2Min. The only triggers that use this module are VBF + MET and VBF + Tau triggers.

The VBF + Tau triggers under development are
HLT_(VBF_DoubleJet115_40)_DiTau_20
HLT_(VBF_DoubleJet40)_DiTau_115_20
HLT_(VBF_DoubleJet40)_+SingleJet115_DiTau_20.
Especially for the third case this change is required.

Note:
The VBF + MET configs should remain unchanged with this addition, since the default setting of pt3Min_ is set to the same as the pt1Min_ used in all of its configurations, namely 110 GeV (see hltL1TPFJetsMatching which is the filter used in all the VBF + MET triggers HLT_DiJet110_35_Mjj650_PFMET*_v and HLT_TripleJet110_35_Mjj650_PFMET*_v).

This pull request is fully signed and it will be integrated in one of the next master IBs (tests are also fine). This pull request will now be reviewed by the release team before it's merged. @davidlange6, @slava77, @smuzaffar, @fabiocos (and backports should be raised in the release meeting by the corresponding L2)
