Update package.json.

Add a couple more properties like bugs.
package.json: Pin dependencies versions.

This was one of the reasons fixmyjs failed on Windows in the past.
package.json: fix test command.

package.json: specify the files to install instead of installing everything.
Add dependency status badges.
Update .travis.yml.
