Using references matches the C++ coding style better and should improve
performance a bit in theory. It avoids 2 copies of T in case of the
functions registered with RegisterFunction (mainy used in the GUI). It
should also avoid one or two copies in case of
DEFINE_INTERFACE_METHOD_X, which is used in the simulation, but I
haven't bothered to count it there exactly.
It is now predefined which types have to be passed by const reference
and which are passed by value. Note that references can't be used as
out-parameters (to return multiple values to JS). This hasn't worked
before either and probably never will.
This was SVN commit r17696.
Hides the summary-button in the replaymenu in case the summary wasn't
saved.
Corrects the timestamp for incompatible replays.
Remove unused UNUSED from header files.
Use string8() instead of OsString().
Mention a reported compiler warning.
Use const& instead of a copy in StartVisualReplay().
This was SVN commit r17356.
