Ethan Atkins 51d986d751 Make multi command parser work with string literals
Presently the multi command parser doesn't work correctly if one of the
commands includes a string literal. For example, suppose that there is
an input task defined name "bash" that shells out and runs the input.
Then the following does not work with the current multi command parser:
; bash "rm target/classes/Foo.class; touch src/main/scala/Foo.scala"; comple
Note that this is a real use case that has caused me issues in the past.

The problem is that the semicolon inside of the quote gets interpreted
as a command separator token. To fix this, I rework the parser so that
it consumes string literals and doesn't modify them. By using
StringEscapable, I allow the string to contain quotation marks itself.

I couldn't write a scripted test for this because in a command like
`; foo "bar"; baz`, the quotes around bar seem to get stripped. This
could be fixed by adding an alternative to StringEscapable that matches
an escaped string, but that is more work than I'm willing to do right
now.
