Remove Boost.Assign & Boost.Bind dependencies and switch to BOOST_TEST

[Flamefire]

Replace Boost.Assign by initializer list and simple helper due to commas otherwise interfering with the macro
Mostly done by Regex-search&replace

This discovered undeclared dependencies on Boost.range

Single file used Boost.Bind -> Also replaced by std::bind already used elsewhere

While at it another S&R to use BOOST_TEST instead of BOOST_CHECK<OP>
