Modernize MuonDet

• avoid copying std::vector unnecessarily
• prefer boost::lexical_cast over sprintf/sscanf
• prefer std::accumulate over explicit loop

@mpalutan @desimone @pgriffit @rvazquez FYI

For some reason this MR contains also the FSRNavigator patch !1262 (merged), so should be merged after it (unless it is rebased..)
