MSVC 2013 and earlier have the _snprintf() function fill fields
completely, eliding the NUL character, if the printed string is
as long as or longer than the given buffer size. This is not the
case in POSIX snprintf(), it always ensures the string is terminated.
This causes several fields in GSI to become truncated and contain
NUL characters which should not appear there.
A lot of the wxDialog subclasses don't actually override any virtual
functions, so there's no particular need for them to be subclasses at
all, and wxDialog's vtable is so huge that they actually contribute
measureable to the size of the executable.
It's modestly faster, significantly more type-safe, and doesn't assert
when there's too few arguments, which causes problems for plural forms.
Closes#1733.
ptr_vector hasn't been updated for C++11, so despite being specifically
designed to store pointers to objects it's less safe and not really any
easier to use than a regular vector of unique_ptrs
