This commit adds support for compiling spew without the unsafe package.
When compiled without the unsafe package, some of the more advanced
features such as invoking stringers on pointers from non-pointer
variables and unexported struct fields are not available.
By default, spew will be compiled in the limited mode for Google App
Engine since the unsafe package is not available there. Additionally,
spew can be compiled without the unsafe package manually by specifying
the "disableunsafe" build tag.
Finally, a new package-level constant named "UnsafeDisabled" has been
exposed which can be used to programmatically determine if spew was
compiled with access to the unsafe package.

Rather than stuffing a ConfigState instance into a separate SpewState,
just add the functionality directly to the ConfigState. This provides
simpler syntax for the consumer.
One side effect of this change is that, unlike a zero value SpewState, a
zero value ConfigState doesn't provide default values which means the
Indent field is set to provide no indentation. The consumer is now
expected to set the indent to their desired value when declaring an
instance of ConfigState.
Alternatively, the consumer can call a new function, NewDefaultConfig,
which returns a ConfigState with default values, including a default
indentation of a single space.
For example, to change the indent to a tab, the previous syntax was:
ss := new(spew.SpewState) // or var ss spew.SpewState
scs := ss.Config()
scs.Indent = "\t"
scs.Dump(whatever)
The new syntax is simply:
scs := spew.ConfigState{Indent: "\t"}
scs.Dump(whatever)

This commit adds a new type, SpewState, which can be used to create
instances with unique configuration options. The methods of SpewState are
equivalent to the top-level functions. Full documentation and examples
are included.
