Update build scripts for artifactory.

Gradle version bump, now DNS works.

Tidy up gradle source sets.

This replaces the default source directories (src/main/java, etc)
with our own, instead of just appending ours to the list.

Add method to FileUtils to get a Path.

This maintains a FileSystem pointing at the jar the application is
running from, which can be used to get Paths for bundled resources.

Use J8 methods in TextFile.

Add a function based validator.

Remove deprecated method.

Tidying

Finish removing ant + netbeans

Tell gradle to use 1.8.

Ditch travis

Switch CI to j8

Add JSR305

Use @Nonnull

Start work on a generic link extractor.

At the moment this just implements the first step of the Styliser's
link detection. It doesn't apply any of the "intelligent" corrections.

These are from the TextPane, but seem fairly general purpose.

Don't try and resole using a path from another FS provider.

Create paths via URIs not via strings, as otherwise it gets
confused with protocols.
