Search, Paging, and "As of" Date (#10)

Issues Fixed:
* Added request search capability (#2)
* Added pagination to search / inactive request lists (#3)
* Added "as of" date display option for requests (#9)
* Updated documentation to reflect the new options and their behavior

Also Fixed (w/o issue numbers):
* Fixed a verbiage error with the confirmation prompts
* Split the I18N for the maintain requests page into its own localized view
* Modified many "magic strings" in the code to use F# discriminated unions instead (stored as single-character codes in the database)
