lib/parse: make parseDecimal "tail" HL
...
HL, instead of being preserved, is set to the character following
the last read character.

parseExpr --> parseExprDE: easy ones
...
Those replacements were trivially equivalent. For the other ones, an
examination of the context is necessary.

basic: make variable A the only input variable
...
Mechanism for assigning inputs to the specified variable is clumsy and uses
binary space. Always using A is much simpler and doesn't seem very limiting to
me. I do that because there's many more "input" commands I'd like to add.

Also, fixed the cmd matching algo to not accept partial matches. For example,
to stop matching "input" when the command was "in".

It can only print a decimal literal. But still, that's a big step because
I hadn't implemented decimal formatting yet.
