Various fixes and improvements to replaying of Continuous recordings.

Browse source 
FGFlightRecorder::replay():
    Fixed behaviour when going back in time while replaying - we were not
    replaying initial property changes correctly because we deliberately
    don't load signals data for some frames when we are only interested in
    multiplayer or extra properties.

    Removed incorrect code that tried to avoid replaying the same frame twice
    in succession.

FGReplay::update(double dt):
    Improved how we figure out which frames we need to replay just for multiplayer
    or extra property changes.

FGReplay::makeTapePath():
    New fn containing the code for converting tape name into path by prepending
    tape dir and appending .fgtape as necessary. Called when loading tape at
    startup or at runtime.

Cached some more property nodes in SGPropertyNode_ptr's.

Don't recordCHAT_MSG_ID messages; unfortunately it looks like most (all?)
chat message text is received as part of POS_DATA_ID messages tied to
sim/multiplay/chat, so this doesn't actually avoid recording chat messages.
