JSON : all user-defined properties are exported as String

[melonjs]

for example :

"properties":
{
   "image":"spinning_coin_gold",
   "spritewidth":"32"
},

this is not consistent with the regular XML export, where spritewidth (here in the example) would have directly the Integer value 32 and not "32".

Actually, this is consistent with the regular XML export, since in XML all data are strings.

Also, all user-defined properties are in fact strings. There is no support for different types of properties at the moment (that's issue #14).

With Tiled 0.16, there is support for basic property types, and numbers and booleans will no longer be quoted as strings in JSON files.
