Subject: Get rid of intostring() and .c_str()
Message-Id: <89ae955518665a61-0-artemis@metatron>
Get rid of the need for intostring() (in addition to tostring()), and having to
place .c_str() after tostring() in rLog calls.
The former is necessary because of some problem with disambiguating which
operator<<(ostream,T) to use when Event is being output, so intostring() calls
T.operator<<(ostream) explicitly. This problem seems to exist only for Events.
It should be possible to solve the latter by returning char* from tostring()
rather than std::string.
