Added support for the following:
- 'Args' value specified in a p4d server block is now also applied to checkpoint and journal file calls. I specifically added this for flags like -C1, which while technically unsupported, is also required on all calls to p4d. I wasn't sure that there were any flags which would be used when starting a server and not when checkpointing (since all other required values are specified as environement variables)
- support for checkpoint/journal prefix. Using the 'CkpPrefix =' in the p4d server block, you can specify a prefix used in checkpoints and journal rotations. Currently the same prefix is used for both.
- support for specifying whether or not checkpoints and journal rotations should be compressed. Use the 'CkpCompres = true' in the p4d server block. ACtually, just the presence of this variable will enable compressed checkpoints. That probably ought to be changed.
- Support for a 'dump' command from p4dctl. I wanted to be able to dump environment settings (specifically p4root, checkpoint prefixes and whether or not compression was used) in scripts that I was writing. I hijacked the Dump() command that was used in debug output.
