Bug 6602 - Reports dictionary doesn't properly recognize text columns

Reports dictionary won't let you set a comparison for MEDIUMTEXT columns. To
test, choose a MEDIUMTEXT column like borrowers.surname in Step 3 of adding
a new dictionary definition. Before the patch, in Step 4 you would not see
any kind of form field for entering a comparison. After patching Step 4 will
offer you a field labeled "Search string matches."

All tests and perlcritic pass.

Test plan:
1) Reports > Reports dictionary > New definition
2) Step 1: Some name
3) Step 2: Patrons
4) Step 3: First name (mediumtext)
5) Step 4: Verify 'Search string matches' is offered.

For both, surname (mediumtext) and first name (text) the program should offer you
"Search string matches" on step 4.
