2012/endoh2/everything.sh -> try.sh and formatting

To make the script more like the other entries I renamed the script I
originally named everything.sh (because there's so much it does and it
uses 'make everything') to try.sh.

The README.md file has been format and typo checked.

This should complete the review of 2012/endoh2.
