Rewrite NumValidator

Browse source 
Split int validating and double validating into two separate classes.

Make double parsing, validating and stringifying locale-aware. This is
far more complicated than it needs to be due to that Aegisub's locale
handling is a total mess.

Use DoubleValidator rather than wxFloatingPointValidator, because the
latter doesn't work with Aegisub's locale mess (on OS X it uses the C
locale for some things, and the locale reported by CoreFoundation for
others).

Closes #1568.
