Allow quotes for hash values

[skytreader]

Allow hash values to be enclosed in quotes. The quotes will, of course, not be saved to Redis. This allows the insert file to be more readable as we can put spaces before the actual hash value without the spaces getting stored in Redis.

Possible complications

What if the value we want to insert to Redis has a quote. We must allow for some form of character escaping mechanism.

And also hash keys? Are spaces allowed in hash keys? :|
