Fixed login screen icon issue

Fixed the login screen icon’s display issues on retina devices.
Made sense of build numbers

XYZAA - Where XYZ is the full version number without decimals, ie.
1.2.3 would be 123; and AA is the build number from 01 to 99. After
build 99, the full version number is incremended by one ie. 12399 would
be followed by 12400, and the full version number would now be 1.2.4.
