Fix bug in installation script

Professor, This PR references issue #40. There is a bug in the script that prevents the "--OODT_HOME--" placeholder substrings from being appropriately replaced by the correct path.

The changes are made to install.sh. Furthermore, for sed to work on Darwin machines, the -i parameter must be updated to include a backup file extension, without which sed will not run. I have added a fix for this as well.

Additionally, we can edit the "Automated Install" portion of the readme - the installation scripts have rendered some of these steps redundant. I can include a doc fix as a part of this issue itself.

Thanks!!

@chrismattmann Thank you professor. Additionally, may I propose the following updated list for the Automated Installation process?

1. Navigate to desired location for imagecat
2. git clone https://github.com/chrismattmann/imagecat.git
3. cd imagecat
4. cd auto
5. chmod +x install.sh
6. ./install.sh
7. Wait for a install to finish
8. cd ../../deploy
9. Add the absolute paths of all images (one image path per line) in data/staging/roxy-image-list-jpg-nonzero.txt
10. ./start.sh
11. ./bin/chunker

12. win

From my experience, only these steps are necessary to successfully setup imagecat.

PS: I also think we can remove the manual installation guide altogether - the manual steps are just picking apart ./install.sh and ./start.sh and doing everything manually, which seems unnecessary!

Yes can you update that?
