Consistently handle wxImage Load_Verbose flag in LoadFile

Browse Source 
In wxImage, it is possible to set the Load_Verbose flag (default) if
messages are to be shown to the user in popup message boxes (via
wxLogError and wxLogWarning).

Unsetting this flag is supposed to remove these message boxes but in
practice, this was only applied in the function DoLoad() while other
messages could be issued earlier in overloads of the function LoadFile().

This commit checks if Load_Verbose is set or not and behaves accordingly
in LoadFile() overloads so that all messages can be suppressed.
