Fix regression regarding timers with equal end-time

Browse source 
std::set<Key, Comp> stores Key only if Comp(Key) yields a unique result (My
mistake: I was under the impression Comp is only used for the ordering). This
prevents FbTk::Timers with equal end-times from actually being started.
Escpecially in situation with multiple ClockTools this lead to stopped timers
(see bug #3600694).

Kudos to Adam Majer for enlightening discussions.
