Fiddled a bit with the code

Functionality remains the same
- replaced JPG handling code with a neater wrapper for JPG file data
- think i changed the helpfile somewhere (typos etc)

busy preparing for a wxWidgets port that will be able to store and display / modify svg data in a simple annotation pane. (only lines, arcs, text maybe)

that would enable drawing / viewing of diagrams to accompany the text.
also would put the code in a more portable framework and add a nifty GUI.

i would keep compatability with the command line version for anything like that. we can split the image data from the text with something like
----IMAGE----
and then lots of SVG tags of whatever you're drawing.

that would also enable people with only the command line version to copy the image tags into an html file to view the diagram with a web-browser (there is obviously risk in that as you need to save the file to disk to open it)

anyway, so exciting things, i feel.
unfortunately the wxWidgets version would probably need dlls and crap in a folder along with it.
i will make a pretty installer to simplify unpacking it somewhere, but it will remain portable.

stil busy getting my head around the wxWidgets framework, but i can see it will work perfectly.
the steg and encryption code in nicely wrapped up and easy to deploy in the new project, so maybe sometime in the middle of next year the GUI version with diagram support should be available.
