SQL wrapper doesn't handle the SQLite type "numeric"

[TheLinx]

I'll make a fix for this right now.

So I was able to fix this very simply.

Just add

function convert.numeric(v)
  return tonumber(v)
end

to the 'model.lua' file right under the convert.number(v) function

and

function escape.numeric(v)
  return escape.integer(v)
end

right under the escape.number(v) function

Can this be added?
