[Koha] Systempreferences table

I've added support for systempreferences via the systemprefs() subroutine in Search.pm and a systempreferences table in the database. The systempreferences table: create table systempreferences (variable char(50), value char(200)); So far, the only pref I'm using is for choosing an acquisition module: variable='acquisitions', value='normal' or 'simple' If the systempreferences table doesn't exist, you'll get errors in the apache logs, but acquisitions will still default to normal. Also, I haven't added my simple acquisitions module to cvs yet. Steve.
