[Feature] Allow for generating files with endings other than .html

[mattstauffer]

Allow Jigsaw to generate files with non-.html endings so folks can generate .js files or .rss files.

Reference: #46 #50

Support for this added in v1.0.0; you can now process .js, .json, .xml, .rss, .txt, and .text with Blade first: http://jigsaw.tighten.co/docs/other-file-types/

Just for anyone else arriving here from the googles, the updated docs link is http://jigsaw.tighten.co/docs/content-other-file-types/

Does this include blade.yml?

It's not mentioned here or in the docs.

No, the only Blade hybrid files currently supported are those listed above and in the docs. Feel free to PR, though; it would require simple changes to the Blade extension arrays in ViewRenderer and InputFile, I believe.
