Release Notes for version 1.9.1.3

This is mostly a hotfix release for a bug introduced with Visual SEO Studio release 1.9 in options windows.
We profited to complete a few changes that couldn't make it for the official 1.9 release date, to make the new Mozscape API integration shine.

For more details on release 1.9 please read: Visual SEO 1.9 adds Moz metrics.

Usability / UX:

• Mozscape API integration: user is now forced to validate credentials before using them (unless they already did).

Various:

• Added missing Polish translations (they didn't make it in time for rel 1.9).

Fixes:

• Settings window: fixed crashing bug that occurred when user clicked on the OK button without having ever selected the new Moz credentials panel.
• Settings window: fixed crashing condition that could have occurred when user changed any value in any options form, without having first visualized Moz panel :(
• Moz options form: after validating credential, the text in "Account Type" field was not localized.
• Some corrections in translations, mostly Polish.
