Installer gives wrong path to icon to documentation shortcut if English is not used for installation.

Reproduce:
- run default installation using German (shortcuts are installed by default)
- check 'JBoss Plattform' in Start menu program groups

Actual:
No icon for 'Plattform-Dokumentation' shortcut.
Shortcut is looking for icon in:

%SystemDrive%\workspace\EnterprisePlatform-5.3.0\jboss-as\icons\docs.ico

Expected:
Path to docs.ico is set to:

%SystemDrive%\workspace\EnterprisePlatform-5.3.0\jboss-eap-5.3\jboss-as\icons\docs.ico
