Bug 14252: (Followup) Fixed issues pointed to in comment #40

Based on Mark's inputs in comment #40 -

[1] selected 'mast' (short of 'masthead') and updated :
   (a) bug_14252-OpacLangSelectorMode_syspref.sql
   (b) sysprefs.sql
   (c) opac.pref
[2] Reduced the calls to Koha.Preference() from :
   (a) masthead.inc
   (b) opac-bottom.inc

After applying this patch, update the database once for it to pick
up the new option values -'both|mast|foot'.
