Add support for output as std::map/unordered_map/set and QMap and QHash,
when giving the full result type as template argument. For std::
(unordered_)map, the function must return a std::pair<Key,Value>, for
QMap and QHash it can also be QPair<Key,Value>.

Can come in handy when the function or member does not directly return
the right value type for the result list, but is implicitly convertable
to it. For example from pointer to class to pointer to superclass, or
from int to double.
const auto result
= Utils::transform<QVector<double>>(v, &ValueType::intMember)

Many STL algorithms have value version. So you can only use a predicate:
std::stable_partition(std::begin(list), std::end(list), [](int entry) {
return entry < 20;
});
With this predicates you can write it in a shorter form:
std::stable_partition(std::begin(list), std::end(list), lessThan(20));
The find helpers are moved to predicates too.

Pass the mapping from custom enum to text style in form of a function,
which then can use a switch which is checked by compilers, and
avoids the need to lookup a different enum somewhere else to find
out what the mapping actually is.
That mapping is cached to keep performance as before.
Also, most highlighters created an enum just for the purpose of mapping
to text styles, basically creating duplicated subsets of text style like
enums everywhere. Instead provide a default, identity mapping from text
styles to text styles.

These take a container and a predicate and return a Partition
struct with the hit and miss fields. Any element in the original
container will end up in either hit or miss, depending on whether
the predicate returned true for the element or not.

Do not require containers to provide a size() method. This
makes for a less optimized insertion into the target container,
but most Qt classes should still handle this ok.
The upside is that e.g. the treemodel iterators can now be
transformed.

Currently e.g. this won't compile:

QString and QLatin1String.
In C++14, equal_to<> (without any template parameter) was added,
which simply works in that case.
