[NonGNU ELPA] New packages: elquery, file-ring, metamorph

[Adam]

Hello!

I have a few packages which might be a good fit for NonGNU ELPA

elquery is an HTML parsing (using emacs' libxml), formatting, and 
querying library, which is useful for scraping. It contains a 
querySelector implementation, and lots of helper functions for 
retrieving/setting data on parsed nodes.

file-ring lets you switch between files which have the same basename 
with a keypress, which I've found useful when writing c and angular code 
(.c/.h and .component.ts/.component.html)

metamorph is effectively a Turing-complete `replace-regexp`, which I've 
found useful when I need to add some number to twenty constants in a big 
header file.

Feedback is welcome and appreciated - thanks in advance!

Thanks,
-Adam
