GH-78: Replace the 'binaryPlugin' attribute with two separate attributes

[ascopes]

Breaking change

Replaces the binaryPlugins Plugin attribute type used for binary plugins and replaces it with
two attributes:

• binaryMavenPlugins - for Maven resolvable dependencies mapping to executables.
• binaryPathPlugins - for executables on the system $PATH.

In addition, the jvmPlugins attribute has been renamed to jvmMavenPlugins for consistency.

Versions have been incremented to v0.3.0 accordingly.

Closes GH-78
