HTML change should only compile changed file

[Psvensso]

Hey guys, just wanted to open this issue to check if it´s a feature/bug or just expected behavior.

I was using grunt-contrib-watch to watch and compile (i have multiple steps so used the contrib watch instead of buildt in). Once i changed a HTML file i could see from the contrib-watch verbose logging that all my HTML partials was being triggered for change. Meaning that grunt-ts recompiles all HTML partials on each trip not just the ones being changed.

I can confirm this by filestructures changed time that all partials have been re-created.

This seems like a terrible waste, i can have a go at a pull request but wanted to run it through here first and see what you guys think.

:bug:

Just because I didn't know better when I started (didn't have a watch fast compile pipeline initially) and haven't used HTML templates for quite a while (moved to angular template cache).

Same issues existed for things I did use e.g. reference.ts and transformers so they got patched. e.g.

https://github.com/grunt-ts/grunt-ts/blob/93e55e51f3675270a6d34818f150e42fd6475ea7/tasks/modules/reference.ts#L101-L104

    // Modify the orig contents to put in our contents only if changed
    // Also Return whether the file was changed
    if (updatedFileContents !== referenceContents) {
        grunt.file.write(referenceFile, updatedFileContents);
        return true;
    }

And https://github.com/grunt-ts/grunt-ts/blob/b633f95295ddf22b28dfb8acd9c23c7bdb44df72/tasks/modules/transformers.ts#L298-L301

        var transformedContent = outputLines.join(os.EOL);
        if (transformedContent !== contents) {
            grunt.file.write(fileToProcess, transformedContent);
        }
