[Issue #1178] Added hook to register content type and highlighting in orion

[svenefftinge]

Fixes #1178.
With this change you can configure arbitrary new contentTypes and corresponding highlight configuration.
Here's a usage example:

@Inject
    protected void configureContentType(final OrionContentTypeRegistrant contentTypeRegistrant) {
        // register content type and configure orion
        final String contentTypeId = "text/x-testlang";

        OrionContentTypeOverlay contentType = OrionContentTypeOverlay.create();
        contentType.setId(contentTypeId);
        contentType.setName("Test Language");
        contentType.setExtension("testlang");
        contentType.setExtends("text/plain");

        // highlighting
        OrionHighlightingConfigurationOverlay config = OrionHighlightingConfigurationOverlay.create();
        config.setId("testlang.highlighting");
        config.setContentTypes(contentTypeId);
        config.setPatterns(
                "[\n" + 
                        "  {include: \"orion.lib#string_doubleQuote\"},\n" + 
                        "  {include: \"orion.lib#string_singleQuote\"},\n" + 
                        "  {include: \"orion.lib#brace_open\"},\n" + 
                        "  {include: \"orion.lib#brace_close\"},\n" + 
                        "  {include: \"orion.lib#bracket_open\"},\n" + 
                        "  {include: \"orion.lib#bracket_close\"},\n" + 
                        "  {include: \"orion.lib#parenthesis_open\"},\n" + 
                        "  {include: \"orion.lib#parenthesis_close\"},\n" + 
                        "  {include: \"orion.lib#number_decimal\"},\n" + 
                        "  {include: \"orion.lib#number_hex\"},\n" + 
                        "  {\n" + 
                        "    match: \"\\\\b(?:false|true)\\\\b\",\n" + 
                        "    name: \"keyword.json\"\n" + 
                        "  }\n" + 
                "]");

        contentTypeRegistrant.registerFileType(contentType, config);
    }

Ok, got it.
For those who wonders, you can just paste this function in your editor extension. That' s it.

Hi,
How can I use this to add syntax coloring support to a new file type I added to Che? Can anyone kindly explain? It is not yet included in the Che doc, so I have no clue how I should use this with Che.

Thank you!
