elexis e1014aad3b Use CGUI& instead of CGUI* so that the 50+ users stop wondering whether or not that is null and can't even be mistaken to add redundant null checks preemptively.
Remove the remaining of such checks after d3e56f0f57 removed 21 of them
already.
2c47fbd66a initialized the pointer at construction time rather than at
random conditional events later.
