More structured xml files

[Sworddragon]

For example filezilla.xml uses entries like this one:

<Setting name="Window position and size">0 390 138 900 670 </Setting>

This is not really structured for a xml file and makes it difficult to understand for a human or an application. In my opinion this entry (and others in a similar way) could be split like this:

<Setting name="Window maximized">0</Setting>
<Setting name="Window width">900</Setting>
<Setting name="Window height">670</Setting>
<Setting name="Window horizontal offset">390</Setting>
<Setting name="Window vertical offset">138</Setting>

I'm also noticing that the same empty settings are saved differently. For example in filezilla.xml the option "Sitemanager last selected" is saved sometimes as "<Setting name="Sitemanager last selected"></Setting>" and sometimes it is saved as "<Setting name="Sitemanager last selected" />". Probably this could also be enhanced to use always only one of these both variants.
