CodeSnip Old Code (SVN)

Fixed spelling of "dialogue" in various comments.

Merged portable version of application into standard version. Portable version is now run via the -portable command line switch instead of a separately compiled program.

Some consequences:
* Same program may report a different serial number depending on how it is being run.
* Need to change codesnip program update web service to take a new "combined" edition and find some other means of passing info about whether CodeSnip is being used in standard or portable mode.

Recreated "parsnip" (v5 development) branch by branching trunk just after updating it with changes in v4.7.1.
