#48 Adding Description property/field

[Kirkkm]

Related to:

Resolves: #48

Description:

Per the issue/request I added a description to the bed's model

Tests:

I wrote a test in the beds/test.py that will create a record in the beds_bed table, one with a description and one with out. I also tested adding a bed with & without a description from the http://localhost:8000/admin/beds/bed/add/ page. All resulted in records being added to the database.

Looks great! Thanks so much.

@capndave Yeah no problem, it was fun to work on django for the 1st time. Learned a lot from this, so thank you!
