Tagging version 0.2.0.

* Bundle the script with `com.stevegrunwell.asimov.plist`, enabling Asimov to be scheduled to run daily. Users can set this up in a single step by running the new `install.sh` script.
* Fixed pathing issue when resolving the script directory for `install.sh`. Props @morganestes. (stevegrunwell#7)
* Change the scope of Asimov to find matching directories within the current user's home directory, not just `~/Sites`. Props to @vitch for catching this! (stevegrunwell#10).
* Added a formal change log to the repository. (stevegrunwell#5)
