Bug 26236: Fix translating interface from DB term to readable term

Bug 26236: Fix translating interface from DB term to readable term

When viewing the logs we try to swith the db values like 'cron' to friendly terms like
'Cron job'

The values we use for building the selectors on the page ar eupper case, but DB values are lower case

If we simply force upper case in the comparison we can ensure we always match correctly

To test:
1 - Enable some 'Logs' setting in System preferences
2 - Perform some action in koha that will log
    Run a cronjob
    Change a syspref
    etc.
3 - Browse to Tools-> Log viewer
4 - Click 'Submit' to see all logs
5 - Note the 'Interface' column contains lower case DB values
6 - Apply patch
7 - Reload the page
8 - Values in interface are now Camel cased and more friendly
