* doc/GetInt.3: Convert argument "string" to "str" to agree with code.

        Also clarified a few details on int and double formats.
        * generic/tclGet.c:     Radical code simplification.  Converted most
        Tcl_GetFoo() routines into wrappers around Tcl_GetFooFromObj().
        Reduces code duplication, and the resulting potential for inconsistency.
