Another patch will follow from the translations SVN, after I figure out how to work with it.
In kwin repo alone, there's another 4MB in savings with funny files like those:
```
kwin/po/ru/docs/kcontrol/windowspecific/tbird-reminder-info.png
[oxipng] Reduced by 768.94 KB (-96.42%) from 797.52 KB
```
Summary:
Right now a few of the window placement modes suffer one or more of the following problems:
- Inconsistency between the text shown in the Window Behavior and Window Rules KCMs
- Title does not indicate what it does
- Awkward wording
- Lack of unity in grammatical mood between the different modes
This patch fixes these issues by improving the strings and standardizing on the descriptive mood:
- Smart -> Minimal Overlapping
- Maximizing -> Maximized
- Cascade -> Cascaded
- Zero-Cornered -> In Top-Left Corner
Strings are also unified between the window behavior and window rules KCMs, and docbooks are adjusted accordingly.
