3.0.0-rc1, defined locally after being referenced with dllimport linkage

[Joel Fielder]

Hi Warren,

Bet you're loving this one!  When building one of my own apps against
3.0.0-rc1:

mystring.h: 
warning: 'Type mysqlpp::String::conv(Type) const [with Type = float]'
defined locally after being referenced with dllimport linkage

Easily solved though... just need to bring conv's definition inline and
move the following somewhere appropriate (with class SQLTypeAdapter;
maybe):

template <class Type> class internal_string_to_number_proxy;
