1. moved handling of "relative" format from "kDateFormatter::Parse" method (where it wasn't working obviously) to the "kDateFormatter::Format" method
2. restored "DateHelper" class, that was removed in 622 diff by mistake

Tested - got 0 and 1 codes, as planned.

Please test again. Also update test plan to include testing of added code fragment: http://qa.in-portal.org/D379?vs=927&id=929#toc .

Don't perform unique validation from TEMP to LIVE table, when parent record isn't yet created in TEMP table.

Detected an issue (SQL error), when validation of sub-item happens to before parent item is saved into the database.

Got JS alert "Copying operation in Temporary tables has failed. Please contact website administrator." If this is popup about concurrent Save attempt - then accepted.

Debug code removed.

Usage of \FileHelper::ensureUniqueFilename was expecting specific version of that method only available in In-Portal 5.2.x.

Fixed case, when "output_format" option was ignored, when image wasn't resized.

Changed test plan to use image helper.

Opening Front-End gives me these PHP warnings:

Handle cases, when slave is too busy catching up with a master.

Combined error messages.

Fixed thrown exceprion messages.

In the themes\advanced\in-bulletin\elements\side_boxes\polls.elm.tpl change poll image output code to:

Removed excessive (array) typecast.

Fixed logic.

Also since task does optimization only, then here we should be checking that persistent setting retrieval with/without fallback code works as before (not covered) + verify performed SQL count (covered).
