some changes on date-patch and translation in german

[fabian2_de]

Here is the german translation for the strings of the date-patch: /plugins/qt-gui/po/de.ts

(I know, there are more, shown by "What's this", but I don't really know how to translate the html-code... I can't just do it like the other strings..)

also I have fixed missing ")"s in optionsdlg.cpp: /plugins/qt-gui/src/optionsdlg.cpp

<       "<tr><td>hh</td>  <td>the hour with a leading zero (00..23 or 01..12 if AM/PM display</td></tr>"
<       "<tr><td>m</td>   <td>the minute without a leading zero (0..59</td></tr>"
<       "<tr><td>mm</td>  <td>the minute with a leading zero (00..59</td></tr>"

<       "<tr><td>zzz</td> <td>the milliseconds with leading zeroes (000..999</td></tr>"
---
>       "<tr><td>zzz</td> <td>the milliseconds with leading zeroes (000..999)</td></tr>"

and I have an advice, the german dateformate looks like the following: DD.MM.YYYY .. I added it to the choices of the patch: /plugins/qt-gui/src/optionsdlg.cpp

Applied in r4704 and r4705, thanks!

About the html code, just translate it like a normal string but don't change the html tags (<tr>, <td>, etc) nor the strings hh, mm, zzz, etc. I changed the string a bit in r4704 to make it easier to translate (by adding some newlines).
