ShowBirthsignMenu

Brings up the menu which allows the player to choose a birthsign. Whichever birthsign the player chooses will replace any current birthsign.

Calling more than one of the character creation menus ( ShowClassMenu, ShowRaceMenu, ShowBirthsignMenu ) at a time causes problems, including frozen controls and CTDs. There must be a pause between calling each menu to avoid any issues.
