enable travis ci release building

[dougbeal]

.travis.yml:

• language should be node_js
• must install sass (gem) before running grunt
• add compress step, needs expand: true to use globbing
• skip_clean: true must be set for the file to stick around
• tags:true

package.json, Gruntfile.js:

• new required grunt packages

readme.md:

• rough directions for building SemPress
• add travis badge

.gitignore: ignore build directory

I wanted the base theme to automatically build before I created a child.

You would need to create a new encrypted token for travis to access your repo so it can deploy the release build.

I used:
travis setup releases
to generate and encrypt the token.

I didn't look in to the wordpress theme upload process, but it might be possible to upload there as well.

Please let me know if you find a way to do so!
