Updated icon and screenshots

- Fixed display of home as it was waiting for crypto/share values to load which caused values to jump. Now we use cached values and update once crypto/shares have updated

Bug Fixes & Improvements - Fixed an issue where decimal values (like share or crypto quantities) could be saved incorrectly on devices using a comma as the decimal separator (e.g. German, French, and other European regions) - Number fields now accept both comma and period as decimal separators, no matter your region - Edit forms now pre-fill values in your region's number format - Minor performance improvements when typing in number fields

Fixed error with changing currencies

- Changing currency in the bank account now saves - Reorder buttons, etc., for a more consistent look and feel. - Some internal code updates to, for example, synchronise to the newest Swift version - Edit an About page.
