D3PDAna: fix access to jets and truthJets with new reader
restore d3pd.trk (trk10 was just a test)
D3PDAna::buildMet access the correct met components

The previous arguments to SUSYObjDef::GetMET were the wrong branches,
so it was compiling fine, but complaining about the missing branches
when running. We are using the 'Egamma10NoTau' MET, which apparently
is appended at the end of the branch name. I probably mis-read the
info at
https://twiki.cern.ch/twiki/bin/viewauth/AtlasComputing/CommonD3PD
Anyway, now it compiles and runs fine; tested for simu and data as
```
test_D3PDAna -f fileList_WZ_ntupcommon.txt  -s WZ_ntupcommon 2>&1 | tee NtMaker.log
```
move SusyNtMaker in the susy namespace
SusyNtMaker: inherit from D3PDAna rather than SusyD3PDAna

By inheriting from D3PDAna, we now access all of the branches through
D3PDReader::Event rather than through SusyD3PDInterface (i.e. we don't
need anymore to add one by one the datamember corresponding to each
collection/object).
Summary of the mapping `old->new`:
```
d3pd.truth. -> m_event.mc.
d3pd.evt. -> m_event.eventinfo.
d3pd.evtShape -> m_event.Eventshape
d3pd.ele -> m_event.el
d3pd.truthMu -> m_event.muonTruth
d3pd.trk -> m_event.trk
d3pd.gen. -> m_event.mcevt.
d3pd.pho -> m_event.ph
d3pd.tau -> m_event.tau
d3pd.truthJet -> m_event.AntiKt4Truth
d3pd.jet -> m_event.jet_AntiKt4LCTopo
d3pd.jetMetEgamma10NoTau ->  m_event.jet_AntiKt4LCTopo_MET_Egamma10NoTau
