Grid module will now display filter row as fixed when the page is
scrolled, along with the header row. Added some more special characters to Stock module grid filter, '<' and '>' characters can be used at the start of the input to filter rows based on column values being less than or greater than the number that follows those characters, respectively. Moved fixHeaderRow() from Stock module to Grid module js and made it generic. It's now also used by the Members module. Made autocomplete fields more consistent by using minLength: 1 across all modules where the source list is local. Summary page can now optionally skip displaying the outstanding balance for a user.
