Improvement - Add user seed words check

[lsji07]

Testing the wallet generation based on 4.7test3 and suggest an improvement to enhance user protection and encourage seed word retention.

Add two screens after the seed words have been generated to test that the user has correctly recorded the seed words. If they fail, return the users to the seed words to correctly retain and secure on paper/other non electronic means.

Screen one tests 1 seed word from a selection of 4 random seed words. Screen must show only the numerical position of the seed word required. User must select the correct seed word to pass.

Screen two tests 1 different seed word from a selection of 4 random seed words. Screen must show only the numerical position of the seed word required to pass. User must select the correct seed word to pass.

Prefer random seed words numerical positions be selected each time the user attempts to pass.

The above is 1 solution, happy to consider other secure means to achieve that end.
