ImpressPages 4.2.6

More options in config, updated translations and many many small fixes.

We always try to make thing more feature rich and  simple at the same time. This time we have made configuration section even simpler. Now there are just two fields in it that are very easy to understand. CRON options are hidden under "Advanced options" link with addition of old emails and old revisions cleanup settings introduced in this release too.

We have many new strings translated by the community this month. All those tranlsations are now included in GIT by default. For those who want to join and make ImpressPages available in their own language, please register on Transifex and start translating. If you do translations on GitHub, that creates us additional job to sync translations with Transifex and cold be the cause of disappeared translations.
