CVSNT 2.5.04 (Zen) Build 2442

* Use md5 to avoid sending large files across the network - files >5mb 
get an md5sum stored in Entries.Extra.  When their timestamp is changed 
the checksum is verified against the stored one which avoids sending 
large unchanged files across the network.  For small files it's quicker 
to send it than do the checksum.  At some point I'll probably make the 
threshold configurable.. 5mb is OK for a reasonably fast connection but 
over dialup the break even point is a lot lower.
* Make cvs diff always ignore the BOM so it doesn't appear in the output
