cvsnt 2.0.19

* ls -T and log -T work to the client's timezone now.
* RCS last checkin time stored in Entries.Extra is now in time_t format, 
so it's easy for frontents to read/format.
* If a previously erased file is re-added, honour the expansion option 
of the new file.
* On OS >Win2k Installation attempts to create a temporary directory and 
set permissions on it rather than use the default.
* General bug fixes.

2.0.18 seemed generally OK, so this is only fixes and stabilisation of 
the features added over christmas.  Time to bash this one and make sure 
it's 100%.
