Update cs-CZ.xml

@XhmikosR 
Perhaps, you can add this line to `run_tabspace.bat`,
```
powershell -nologo -noprofile -command "$x = new-object -type System.Xml.XmlDocument; get-item -path src\Languages\*.xml|foreach-object { $p = (resolve-path -literalpath $_.FullName).ProviderPath; $x.Load($p); $x.Save($p) }"
```
