Fix compatibility with Boost versions before 1.54

Before 1.54, there was no support for varadic calls to boost:call_once(),
so make the arrays static members to avoid the need to pass them to the
static init methods.

Fix compatibility with Boost versions before 1.54
Fix StandardTokenizerImpl.cpp compilation.

8628278 broke compilation due to a typo (boost:call_once instead of
boost::call_once). Additionally, VC++ compilation with precompiled
header was broken, because LuceneInc.h must be included as the very
first header.
