Add porosity of snow and water ice #923

[kaiiam]

Address #923 adding porosity of snow and water ice to EA design pattern. I think we'll have the large diff issue as I added this on a mac, and the presumably the last useage was on a PC, so we'll get the issue of the line endings changing the whole file instead of just the 2 lines I added. @cmungall was annoyed about this in the past.

See OBI keeping-things-tidy for how they deal with this issue. Perhaps worth having if the PC/Mac line ending caused diffs are a problem for us.

Also Previously when I had used this pattern I used my own ID range (not 0 padded) for the IDs, but when @cmungall set this up he gave it an id range which I guess is the right way to use IDs for this pattern, so I picked up at the next one e.g. ENVO:09200034 for this PR.

We default to UNIX line endings now - one of our docs should be a style guide for these concerns - thanks for spotting @kaiiam

Looks good - would you mind rebuilding the OWL module so the classes are available in the editors' file ?
