v0.25.2

Fixes

• Fix curl installation instructions
• Make sure that nvm reinstall-packages system has the right std output.
• nvm reinstall-packages: On systems where npm ls -g --depth=0 does not include npm for some reason, make sure to filter out (empty).

Enhancements (not worth a minor bump)

• Add wrapping curly braces to ensure that the entire scripts are downloaded. If the closing curly brace isn't present, the script will error out.
• Add undocumented nvm debug to print out helpful debugging info.
