should remove old special treatment for 'include' keyword

prior to the addition of the #include dictionary directive (with OpenFOAM 1.5) the special include keyword was used. This has been left in since then (for backward compatibility), but I think that it can finally be removed.

Votes please: @andy @Mattijs @Sergio

What was it used in? Can't find any examples in e.g. 1.4.1.

No examples, just line 66 dictionaryIO.C from the 1.4.1 version. This behaviour was included in 1.5 for compatibility (in case someone was using it at the time). But after 10 years, nobody even knows that it was there, let alone uses it.
