better pretty-print of "symbol already bound" message
initial commit of extempore-repl.el

name changes from ielm.el, but that's all.  this is just here so that I
can easily see what's changed from the original
add "exit on compiler error" behaviour when precompiling
improved REPL (in Emacs)

more robust, and includes host:port in the prompt

back working again

was incorrectly setting the filter list as global, not buffer local

remove modeline process from Extempore REPL

colored host and port in REPL prompth

REPL: getting close

WIP: getting error messages about comint prompt face

remove buggy comint-prompt mangling
make extempore-repl start an Extempore process (in an *extempore*
buffer) if none is running
add "switch-to-extempore" keybinding to repl-mode map
add extempore-start-repl alias
add polymorphic string_cat (up to 8 strings)
remove extras/extempore-repl.el

repl code is back in main extempore.el
add C-c C-j binding for extempore-connect
emacs evaling refactor: send region as a series of defuns
don't switch to extempore buffer when starting up
remove 'disconnect-all' keybinding - was interfering with mark-jump stuff
