Add Journal Entry

[joshdbarton]

As an introspective person I would like to record my thoughts so that I may revisit the later.

A Journal Entry should have:

• A title
• Text content
• A creation date

Given the user is viewing the Journal Management menu
When they select the option to add a journal entry
Then they should be prompted to enter the new entry's title and content
Then the new journal entry should be saved to the database with the current date and time saved as the creation date
