(svn r18045) -Fix: GCC 4.5@HEAD not compiling OpenTTD anymore because of a "non-placement deallocation function [is] selected for placement delete", or in other words delete(void *, size_t) is 'magic'.
We implemented these delete(void *, size_t) operator functions because MSVC warned that "no matching operator delete found; memory will not be freed if initialization throws an exception" for new(size_t, size_t).
This disables MSVC warning about this because we do not use exceptions in the (constructors that use the) overridden allocation functions, as such they will never be called; delete(void *) remains necessary though.

(svn r11981) -Fix [FS#1698]: Use unicode glyph mapping to fix up missing/shuffled sprites in original data files instead of shuffling or skipping
sprites directly. Some required glyphs were not loaded.
-Fix: Large capital U with grave (Ù) along with some other glyphs are broken in the original data files, so do no display them.

(svn r10114) -Fix: Only load newgrf error messages if the language matches the current
language. Since only one error can be loaded anyway, if the language didn't
match you'd get "Undefined string". Also since we're only loading one language
there's no need to use AddGRFString any more.
