Enhancements for Account Security features

[lmsv-mx123]

Follow-up for issue #41 .

Basically had been found out that in the registration part (notably) but also in the other places where the username is sent for account security, the hashing algorithm used to pass in username treated all letters as lowercase. There are several issues in that, for example not being able to have a username with capital letters after the first one. Another issue is for example if you have Aplayer and aPlayer, both should be distinct, but if logging in like aPlayer and doing some account security change or recovery, will try to find for Aplayer and apply it there. To fix it, there must be new hash placed, which maintains capitalization of letters by default even vanilla settings.

A side note enhancement will be the centering of the confirm cancel recovery request, which in general should also apply for other input popup boxes probably
