Fix #204. Go to step definition from a feature file with CTRL+click

[qvdk]

Hello,

This PR allows to use CTRL+click on a step to jump into its definition, as F3. (#204)

Known limitation
As #285, only built-in cucumber expressions (with built-in parameter types, or with regular expressions) are supported. The plugin lacks ParameterType detection for now.

An other example with lambdas

This is really good! 👍 Just wondering, why should it not work with RegularExpresions? AFAIK the CucumberExpresionParser used also support the old style regular Expresions?

[qvdk]

@laeubi I misspoke. This works with regular expressions and cucumber expressions.

However for this last, only cucumber expressions with built-in parameter types works, for example Add {int} item to chart.
But I choose {color} will not.

Because of a limitation in the step parser during the step definitions detection. This one use the ExpressionFactory with the default ParameterTypeRegistry of the file local.

Snippet from cucumber.eclipse.steps.integration.Step.setText(String)

this.expression = new ExpressionFactory(new ParameterTypeRegistry(locale)).createExpression(text);

In order to support custom parameter type, the plugin should retrieve all ParameterType available in the classpath, then register them to the ParameterTypeRegistry.

Thus, #285 and #290 will support the cucumber expressions with custom parameter type.
