Subject: QColor: plaster API with Q_DECL_NOTHROW

This is mostly straight-forward, but some things are worth noting:

1. Yes, this is necessary. The noexcept operator looks for noexcept tagging,
   not at the contents of the function to determine whether to return true.
   The more conditionally-noexcept functions are used, the more important it
   becomes that low-level classes are correctly marked noexcept. In that, it
   is like constexpr.
2. In accordance with the rules governing noexcept specifications for the
   standard library itself, the get*() functions, as well as any function
   taking (but not returning) channel values as ints or qreals, or taking
   QStrings are not marked as noexcept, since they have preconditions and
   thus a narrow contract. Narrow-contract functions should not be noexcept.
   All other functions have wide contracts (ie. no preconditions).
3. Any function returning QString can throw (bad_alloc).
   Consequently, they, too, are not marked nothrow.
