Jira Goodie first (incomplete) version

When a JIRA bug ticket number is searched, this goodie
checked if the ticket is owned by a project hosted on the Apache JIRA bugtracker
or on the Codehause JIRA bugtracker.
A JIRA ticket is formed by a KEY (corresponding to a project) and
a ticket number. The validity of the key is checked before displaying
any result (comparison with hard-coded keys).

This version is runnable but is still incomplete because not every project key
has been added yet.
Modify metadata in Jira module
Update JIRA projects data (key, name)

Data imported from Apache and Codehaus JIRA bugtrackers.
Delete redundant tests for the Jira module
Hardcoding every project key in the regular expression

The search for the project name is dropped, but the function as
implemented now is much simpler and cleaner.
Remove header for it provides redundant information
Display the project name in the result template
Uppercase ticket name in the result whatever the input is
return text => undef rather than an empty string
only add <br> when multiple results found
