This has a couple of benefits: 1) it is clearly visible to the user that
the list is filtered (doesn't display all the torrents) even when filter
bar is hidden, 2) doesn't lead to filter bar controls being shifted to
the left/right as when "Show:" label text changes.
We don't currently (if ever) provide context help, so the button is
useless. Moreover, on Windows 10 it's even larger than before and
sometimes title text doesn't fit because of it.
Split FileTree.{h,cc} and FilterBar.{h,cc} files so that each class
is in its own file.
This breaks translations (some classes got renamed => context changed),
to be fixed by next commit (along with Tx sync).
Use latin1 encoding most of the time where default encoding was used
before. Qt 4 assumes latin1 by default while Qt 5 uses utf-8 which is
not what we want.
Use utf-8 encoding in some places where default encoding was used before.
This includes strings coming from RPC.
Fix an issue with SortMode::names[] (filters.cc) where missing comma
between "sort-by-queue" and "sort-by-ratio" resulted in two array entries
being merged into solid "sort-by-queuesort-by-ratio" string and all the
following items being shifted compared to their enum counterparts.
Among other things,
* fix turtle icons size (20x14 -> 16x16)
* use QIcon states instead of changing the turtle icon ourselves each
time (unchecked - off, checked - on)
* make speed limit action in tray menu checkable
* simplify status bar buttons drawing and use QToolButton instead of
QPushButton
Make squeeze labels (used for values on Information tab) display tooltip
on hover if their text doesn't fit. Make selective labels (same as in
GTK+ client) text selectable with keyboard in addition to mouse.
Prevent dialog width growth occured before to fit long error texts.
