This commit is a squash of the commits of TDE/tdebase#331.
In short, this backports some improvements to existing electric border
functionality from KDE, adds the snap tiling (or aerosnap) feature and
brings rudimentary support for active corners, which will be fully
implemented in a later PR.
The options dialog and the documentation has been updated to reflect
these changes.
Additionally, a new relevant option is introduced: an option for
restoring the original size of maximized/tiled windows when the user
starts dragging them. The option is set to be off by default,
preserving the traditional behaviour of KDE 3.x/TDE.
Last but not least, the term "electric" in relation to borders and
corners is replaced by "active" for clarity to the users.

1) Add conflicts check for hotkey checkboxes
Due to the ability to set multiple keyboard layout switching hotkeys,
it is important to inform the user of conflicting options that are
not handled properly by the X.org server when set at the same time
(e.g. Win+Space and Alt+Space).
This change adds a warning that informs the user about the problem and
the conflicting options. This warning is shown only when setting
multiple hotkeys via the Xkb options tab, which is for the advanced
user. Most users will ever need only one hotkey, and the combobox on
the first tab should be more than enough.
2) Add "none" item to layout switching options
3) Replace Reset old options checkbox with radio buttons
As per discussion, this makes the function of the option more
apparent. WhatIs hints have been added for additional clarity.
4) Update hotkey combobox per server options
5) Avoid duplication of options by querying Xkb for already set options.
This was a problem in Append Mode in which `setxkbmap` strings would
get too long due to setting already set options. This code checks for
already set options and omits them from the new `setxkbmap` call.
This does not apply to Overwrite Mode.
6) Overwrite previous grp: options when using the combobox
See previous commit message about the addition of hotkeys combobox.

1) New layout switching approach
The new approach is based on the "grp" options group of Xkb
and so enables us to use predefined X11 layout (group) switching
hotkeys like "Caps Lock" or "Shift+Alt" (you can see the full list
in the Options tab). The added bonus to this is that we conform
to the Xkb setting.
The code lets Xkb handle the keyboard layout switching hotkey(s)
and is similar to the one that is used in kkbswitch, monitoring
for an Xkb group (layout) change event.
This solution required me to remove some hacky and obsolete code
which was there to support really old pre-XFree-4.2 era systems
and included the "include groups" hack.
This means that the "Enable latin layout" checkbox is now gone
and setxkbmap is only called when the keyboard layouts and/or
options are modified, and not for every layout change.
2) Common layout switching hotkeys combobox
A combobox was added to the first page of the Keyboard Layouts
KCM module. It provides to the users a quick way to set a layout
switching key combination. It also controls the "grp" group in
the Xkb tab.
A special note about this combobox is that, even if Append Mode
was selected in the Xkb Options tab, this hotkey will overwrite
previous hotkey options. This means that all grp: options will
be forced removed before applying the option from the combobox
(in contrast to specifying options via the Xkb Options tab,
which, in Append Mode, will not get overwritten until next login).

1. Prefer XML files for Xkb options, as on some systems they have the a fuller
set of options with descriptions than plain Xkb rules files.
2. Various hacks to improve descriptions of newer Xkb options
