Changes in recent versions of herkforth

When you save, it tells you that it saved, and keeps the i/o history at the bottom
tab completion
added a normal search-forward
attractor animation (see herkforth fun)
compiler detects compiling a call to a word that has not been defined yet, and puts the cursor on it
the "go back" feature improved to handle moving next/previous words and next/previous blocks well.
fixed sin() to handle parameters so that $10000 is one radian
saving and loading directly to a harddrive under OF
output logging to a data object
workable one-line string editor (just typing and deleting off the end)
Mac OS X port working mostly.
You can enter "special" characters in strings by entering the hex code and typing ~

fixed bug (in herkforth-0.7 only) that stopped you from creating new variables
added silly example code to shuffle a deck of cards
fixed documentation on some of the herkforth command keys
back stack is persistent (you can still go back with shift-C even after saving)
html export works again (and is now fast)
strings are starting to be supported. you can create them with " and retype them by putting your cursor on them and executing edit-string. More to come soon I hope.

bug: can't create variables. Please use herkforth-0.7.1 instead.
rewrote bootstrapping code so that data words can be moved and resized, so the CFAs for old words are cleared and unused dictionary entries are blanked out completely.
separate key for deleting words, than for deleting characters on the input line (oh, added minimal editing on the input line)
color keys can be used to change the color of existing words
save to a binary capable of booting! works in PearPC emulator (but PearPC is abysmally slow at updating the screen)
adding string support (statically compiled. can't change size)
"find next" key
fixed two crashing bugs that would sometimes crop up after saving.
export source to html/css
lookup branch tables now have a default that is executed when the key is not found.
fixed new-block

jump to a given block number (type it and press shift-E)
error message instead of segfault when you try to execute a word (by typing it and pressing enter) that has not yet been compiled.
create variables in the editor.
fixed crashing bug in the back stack.
you can add blocks with new-block (oops, it's broken. try a newer version).

search for a definition (type word, and press shift-D)
herkforth export-source (export to ascii source from within herkforth) This makes it so (I think) all future work can be done from within herkforth!
added card game (see herkforth fun)
