Highlight defstruct and Actor, Base modules
Added highlight for unless and Task module

Also fixed Agent module name.
Remove grammar clause for "fn" terminal. Fixes #7

After stepping through SMIE functions with EDebug, I realized the only
actual problem in indenting blocks like these is that for the sake of
the grammar, `fn` is considered an opener. I tried many ways to get this
particular issue sorted out, but the simplest was just to remove that
clause from the grammar.

Merge pull request #50 from mattdeboard/indent-fn-in-assignment

Remove grammar clause for "fn" terminal. Fixes #7
Add tests that capture the failure state.
Remove failure expectation.
Replace defunct syntax with valid function definition syntax.
Tidy up a couple very long lines.
Make a test that is expected to fail actually fail.

`indents-last-commented-line' was passing unexpectedly. The example in
the test differs from the example given by
https://github.com/elixir-lang/emacs-elixir/issues/27. The latter does
cause the expected failure in the test.
Add expected result to all failures.
Capture specific grammar error around 'end' statement.
Fix typo in test that lead to false failure.
Remove expected failure statement.
Remove unnecessary newline
Use correct syntax highlighting for use/require/import
Add a SMIE rule function for "def" tokens.

This function now explicitly sets the indentation level of lines
beginning with "def" to 2. Formerly, this token returned `nil` (the
default, because there was no matching pattern in `elixir-smie-rules`),
which caused SMIE to call `smie-indent-after-keyword` to calculate the
indentation. This function was returning the incorrect value which was
causing the inappropriate alignment to the `.`.
Some code cleanup.
