Instant Preview of release notes on the generate page.

[dipanm]

Currently release notes can be crafted (and formatted) under multiple formats including textile, HTML and plain text. As a process, one is supposed to copy that and paste it somewhere - only later to realize that some formatting gone wrong when release notes generated and that becomes a little cumbersome.

Ideally, in the frame below where release notes are displayed, it should also show preview (at least for HTML and Textile) along with the original.

Unfortunately, the current system now no longer recognize these formats as an explicit formats so we need to define what preview format should be.

I've solved the HTML rendering issues and now the format named "HTML" (the format name must be written correctly is rendered directly inside the preview and on clicking the raw output link - see here:
