Upgraded jquery and fixed autocomplete bug

Upgraded jquery and jquery.ui to the latest and greatest.

Also fixed a bug in the autocomplete that was not
allowing us to show the member's full name.
Merge branch 'master' of https://github.com/mariposacoop/IS4C
Updated account and member autocomplete for new version of jquery

New version of jquery severely broke our autocomplete feature. Changes
in this commit resolves this issue.
Removed extraneous error_log entries
Replaced call of array_to_json to built in json_encode
Moved ToggleReceipt from preparse chain to parse chain
Changed jquery ui theme to something closer to our old look and feel
Fixed bug. Removed error message with empty register input.

The register was printing an error message if the cashier just
hit "enter" at the input box. The error was caused by the ajax
parser, which was failing to return valid json on this input value.

This fix makes sure that the ajax parser returns valid json (an
empty array) when the input passed in is an empty string.
Fixed bug introduced by last commit
Fixed big in Void.php that allowed untotaled tenders

In some circumstance it was possible to issue a tender
immediately after a void. This update fixes that bug.
New cron task that will clear out temp trans nightly
Merge branch 'master' into errorfix
Made cleartrans.php executable
