E.g. in split editors with small main window. We now have line edits
with a minimum size and use a flow layout for the replace buttons (which
will reduce width when necessary by laying out vertically).

Flow layout is taken from the Qt examples.

this is where it belongs, rather than into some arbitrary editor.
as a nice side effect, now not only the "rename symbol", but also the
global search&replace has such a warning.

this allows adding further widgets to the layout. see next commit.

When searching the search result window the current item was ignored in
the search instead of potentially being the first match.

Adds a showWrapIndicator(parent) method to IFindSupport, to be used by
implementations. First implementation is given for the BaseFindSupport
that's used for all searches in Q(Plain)TextEdits.

... instead of running a sed script over a lot of files on each
version increment.

qtLibraryTarget is only defined if used with TEMPLATE=lib, which makes
it fail in pri files that are used for app pro files. The tests still
don't run because of run time linking issues.

There was an off-by-one error for the normal find scope.
Improved look by ignoring the left side.

Should have been done earlier. 2.1.80 was burned in the pre-2.1.0->2.0.1
days, and we'd like to have odd subminor for 'working' and even subminor
numbers for pure cherry-picking release branches anyway.

 * Fix all warnings about non-explicit constructors except for those

Block selection was "broken" when using tabs, or rather
incomplete: It treated tabs as normal characters, which
has shown to be unexpected by people using tabs in code.

The new implementation has a vastly improved find scope
as well. In addition, creating a blog selection with
mouse or keyboard feels a lot more solid now, as the
actual selection is detached from possible valid cursor
positions.

Using more *::Constants::ICON_* where it makes sense and
wrapping the file names into QLatin1String where they were
missing.

The increased usage of the ICON constants needed a few more
cross plugin includes of *constants.h, here and there.
I think that it is OK, since the dependencies were alredy there
icon resource wise.
