For aliases, only set couplet for the last verse, if the original verse
has its couplet set. Otherwise, the alias could have trouble with
piping.

The last commit (1415c8f9b89699000ef8d864ff8f0e1bebca4a5f) fixed the
issue with pipes, however, it did not fix it for IO. This patch adds
some logic for the aliased verse to inherit the properties of the
original verse, so that recite works properly for all verse types
(regardless of IO, couplet, or meter).

Fixed a regression that was introduced in:
1415c8f9b89699000ef8d864ff8f0e1bebca4a5f.
Moving aliases to read() broke how pipes worked. This commit removes the
troublesome append!() macro, and replaces it with some logic in the
add() function (impl Appendable for Poem).

This patches fixes a bug, where sometimes, when a Rune::String was
detected, the resulting string from the string!() macro wasn't getting
pushed to the current verse.

Instead of handling aliases in the recite() function, which requires two
loops to handle properly with the current implementation, offload
checking for aliases to the read() function.

The parser will now interpret the '#' character as a single-line comment
string, which works on it's own line, or at the end of an existing line.

Remove some commented out code, that is no longer needed after the
parser overhaul.

Rebuilt the LR parser (i.e. read()) from the ground up. This required
that some changes be made to recite(), in order to accomodate the new
data structures. These data structures were each split out into their
own file, in order to make working with each component a bit easier.
In addition to reworking the parts of the parser already present, some
new features were also added, such as:
- Support for strings (' and ")
- Support for environment variables ($)
- Support for interpreting tild as $HOME (~)
- Support for sub-reading and sub-reciting (`)
Notes:
This is a huge commit that changes almost the entire program (main.rs is
still the same, except for imports). Ideally, huge sweeping changes like
this should not occur on the codebase, but since this is still
pre-alpha, I guess this is acceptable. This is far from the end of
patch set, however, as there is quite a lot of cleanup that needs to be
done. For instance, checking for internal poems and environment
variables should get split out to their own functions/macros. There is
also some defunct code (that's commented out), that is unlikely to be
useful in the future.
