Sanitize.php, FillStoreForm.php,  Store.php, Manual.rst: Corrections. Replace 'sanatize' against 'sanitize'.

New option 'translateIdColumn=feIdContainer' implemented to translate table self referencing ids.
FormAction.php: collect translateMap during copying slave records. New function translateId().
formEditor.sql: Update to latest copyForm Version.

QfqForm.js: Preparation for client, to handle window.location.replace() by new API status 'url-skip-history'. Also changed "(data.redirect === "url" || data['redirect-url'])" to "(data.redirect === "url" && data['redirect-url'])" - CR did not understand the former logic ('or' instead of 'and'). #OPEN#: window.location.replace = 'index.php....' throws an JS exception that it the attribute 'replace' is readonly. Instead "window.location.replace('index.php....')" works as expected.
PROTOCOL.md: add 'url-skip-history'.
save.php: recode to become more readable.
QuickFormQuery.php: getForwardMode() - temporarily fix to update status 'page' to 'url' (bug never caused a problem as long as '||' has been used on client side). Will change 'page' to 'url' asap.

New Version v0.17.5.
