Right now we have a usability problem: the Digital Clock applet has two
ways to let you change the timezone displayed in the applet itself, but
has no easy link to the correct way to change the timezone systemwide. As
a result, users change the timezone in the clock and wonder why times are
wrong everywhere else throughout the OS.
This commit removes the feature of changing the timezone in just the
clock, and replaces it with an overhauled Time Zones page in the config
dialog and a new button in the popup that links you to the Date & Time
KCM where you can change the systemwide time zone in the correct way.
I anticipate that this may cause some grumbling from people who currently
use the "mouse wheel to cycle through timezones" behavior, but now that
all the timezones and their times are displayed prominently in the popup,
you can just click on the applet to show the popup instead of rolling the
mouse wheel over it to cycle through times; it's different, but no worse.

In kde4 times, the layout of clock's tooltip was nicely arranged using a
table. Now it's a bit of a mess so this brings back some nice layout.
Also simplifies the timeForZone function which is used only for the
tooltip.

Adds a simple QSortFilterProxyModel on top of TimeZonesModel and
reimplements filterAcceptsRow using QStringMatcher (supposedly faster
according to qtdocs).

FIXED-IN: 5.3.1
Not all zones have '/' so the splitting may not result in list of two
entries. Use last() instead of at(1) to avoid possible out of bounds
assert.
BUG: 339411
Still has couple missing features:
* no time in the tooltip yet (needs larger refactor)
* no order selection
* no default timezone (but last used is always saved)
* couple minor issues
