Make Cargo rebuild when a peg_file! source file is modified.

Have the `peg_file!` macro register the file in the compiler’s codemap.
Cargo only looks at the modification date of files in this map
to decide whether to rebuild something.
Bootstrap: revert changes when second compile fails.
Add \U + 8 hex digit escape sequences.

Use case: match all non-ASCII characters with [\x80-\U0010FFFF].

The syntax is the same as in Rust.
Add an upper bound for repetition count. (But no syntax for it yet.)
Add e{n} e{,n} e{n,} and e{n,m} repetitions.

Fix #16
