Transformer: Add try-with-resources Java 7/9 language support, #53
f9e9b1f 
It turns out we somehow missed try-with-resources Java 7 support, and no
one has complained yet. This adds support for the Java 7 case, as well
as the Java 9 more concise syntax if the `try` is initialized with a
name expression resource instead of a variable declaration.

Tests: Add negative test for Java 9 underscore identifier, #53

This adds a new xUnit Theory for tests that are expected to fail
parsing.

Transformer: Support converting default/private interface methods, #53
3e0d3a7 
This converts interface methods with a body, such as default and private
interface methods, to C# 8 interface methods with bodies.

Also, this cleans up some use of modifier keyword determination that was
messy as a reult of the JavaParser upgrade.

Java 9 support should be complete, and then I should be able to get through Java 11 (and thus Java 13) pretty quickly. Switch expressions might be a little more involved.

Tests: Add test for Java 10 type inference, #53
4acdb61 
This was already accidentally supported, but now we're making our support
for type inference explicit and under test.

Tests: Add parse test for Java 11 lambda parameter type inference, #53
be31aa7 
Just like regular type inference for Java 10, we already accidentally
supported this since `var` is the same in both languages. In this case,
we cannot make this a full integration test due to some issues noted in
the test file comments.

Java 10 and 11 type inference was already implicitly/accidentally supported, but added tests for those. We can now say that, bugs notwithstanding, we should have support for converting up to Java 13 code, including Java 11 LTS. I will break the other features out as separate standalone issues since they are larger.

Separate issues created for Java 14-21 features.
