This makes it possible to do a bunch of things without
having to keep touching the light button.
I don't really see any downside with this. If you want
the light to go off, just stop touching buttons.
* Calculator face with guess a number
* Add more functions, cleanup, and blinking
* Display operations better in the first location
* Clean up stack behaviour
Add empty stack behaviour, check stack bounds, add stack operations.
Also, make 'mode' always work to switch through faces on entering calculator
(i.e. by defaulting to OPERATION rather than NUMBER).
Some edge cases.
* Tweak negative rounding behaviour; add basic doco
* Add copyright name.
* Flip ordering of binary operations
* Fix compiler warnings
* Remove watch_private_display hackery and give face a better name
Also, slightly clearer documentation and a dupe function.
If you moved away and back to these faces, you'd lose the indicator. Not that the indicator here
seems very valuable, since it's not displayed on simple_clock_face, but at least
this makes things more consistent.
* Make countdown face reset to 0
It was annoying to have countdowns less than DEFAULT_MINUTES.
Admittedly, this does make DEFAULT_MINUTES fairly useless, since
we only ever see it the first time...
* Undo accidental change to movement_config.h
Makefile != bourne shell, I think.
At least on my systems, this was causing a raw -j, which meant
that make had no restriction on its parallelism
(i.e. tried to build everything at once).
I know this is mostly going to be in the website, but I was initially
confused about how to get things going, and it seemed worth
having some simple 'getting started' here.
