Added const qualifier to MuCString.

Now MuCString is a (const char*).  It has always been intended
that MuCString instances are not to be modified.  This change just makes
it explicit in the type. just ignores the const qualifier.

``MuCString`` is the 0-terminated C string type.
``MuCString`` is the 0-terminated C string type. A ``MuCString`` points to a
constant string. Mu never modifies the string passed into Mu from the client.
If Mu returns a ``MuCString`` (including aliases such as ``MuName``) to the
client, the client must not write into the string content.
A Mu instance is represented as a pointer to the struct ``MuVM``::
