· Removed:
· Tab bar is hidden in landscape (not much useful on an iPad)
· Swipe to change between tabs (can interfere with other gestures like swipe to delete, etc)

* This change made the iOS minimum version to be 10.0.
The old saved codes will be converted to the new 'system' and you shouldn't lose any data. The conversion process shouldn't take any long

- Short Version:
· New: link shortener in the Generate QR tab (read all the changelog)
· Fixed text vertical position in the Generate QR tab text box, fixed in-app review prompt and text in Recents tab is fully vertically centered.

- Long Version:
· When generating a QR Code from a web link, the app can generate a short link for you, as well as its corresponding image, useful for large links*
· The text in the generate QR tab is not centered vertically if the device is in landscape mode and isn't an iPad (this avoids the text being hidden in landscape mode in a phone when keyboard is visible).
· Fixed issue where the prompt to request an in-app review may appear when in landscape in the Generate QR tab, instead of appearing in the Recents tab
· Now the text of each saved code in Recents tab is completely centered vertically :D
· When generating a code, then going to the recents tab and going back to the generate QR tab, the saved code would disappeared from the Generate QR tab (something expected), now it disappears faster

* The way it works is simple, just generate a QR code, then a small notification will appear with the shortened link and the new QR code. You can tap on it to load the new code in the tab or 3D touch on it to do some actions if you like.
