Fixed a fatal error about Jira_Project::UPDATED_AT
Implemented DAO_JiraProject::getByJiraKey($key)
Increased the issues, statuses, and versions JSON text field max sizes on jira_project records.  They were TEXT previously (64KB) and now they're MEDIUMTEXT (16MB).  Large projects could easily have JSON larger than 64KB for versions or issues, particularly when issues return the 'create fields' schemas.
