Treat parse conflicts as errors in grammar compilation
...
For now, only reduce/reduce conflicts w/ no tie-breaking precedence
are treated as errors. The rest are dropped, because shift/reduce
conflicts are currently very common because we don't have a way
of specifying associativity along w/ precedence.

Revert "Remove the separator characters construct"
...
This reverts commit 5cd07648fd .
The separators construct is useful as an optimization. It turns out that
constructing a node for every chunk of whitespace in a document causes a
significant performance regression.

Fix error in document editing
...
When breaking down the stack in parser.c, the previous code
would not account for ubiquitous tokens. This was a problem
for a long time, but wasn't noticed until ubiquitous tokens
started being used to represent separator characters

Remove the separator characters construct
...
Now, grammars can handle whitespace by making it another ubiquitous
token, like comments.
For now, this has the side effect of whitespace being included in the
tree that precedes it. This was already an issue for other ubiquitous
tokens though, so it needs to be fixed anyway.

Allow multiple top-level nodes
...
Now, the root node of a document is always a document node.
It will often have only one child node which corresponds to the grammar's
start symbol, but not always. Currently, it may have more than one child
if there are ubiquitous tokens such as comments at the beginning of the
document. In the future, it will also be possible be possible to have multiple
for the document to have multiple children if the document is partially parsed.
