Moved handling of regressions to adapter's code. Partialy resolves benderjs/benderjs#14.
Simplified test builder after core meta builder modification.
Simplified pagebuilder and moved code serving regressions information to Bender core.
createTestsForEditors do not multiply special methods like 'init' or 'setUp'.
Added methods setHtmlWithRange2 and getHtmlWithRange to bender.tools.
Made bender.tools.getHtmlWithRange() use element clone to preserve DOM structure of the original element.
Fixed: setHtmlWithRange2 does not purge markers in case of invalid range.
Simplified: text marker detection and replacement in setHtmlWithRange2.
Renamed getHtmlWithRange -> getHtmlWithRange2.
Added methods bender.tools.set/getHtmlWithSelection2.
Renamed in bender.tools: set/getHtmlWithRange2 -> set/getRange, set/getHtmlWithSelection2 -> set/getSelection().
Fixed: Prevent selectionChange from being fire in bender.tools.setSelection until selection.selectRanges is called.
Fixed: Use absolute reference to methods to avoid failures when called statically.
Fixed: Leave the decision whether to use bender.tools.fixHtml or not with bender.tools.getRange up to developers.
Fixed: Throw error in bender.tools.getSelection if there's more than range in the editor.
