(MODULES-6528) Change registry::value types

 - Fix the bug introduced in 48a0b07
   that did not have lenient enough typing for the $data parameter to
   the registry::value defined type.

 - This commit adds support for numerics, which are necessary for
   dword and qword. It also adds support for arrays, which are always
   an array of strings (corresponding to REG_MULTI_SZ).
