Isoptikon 1.1

The new release 1.1 corrects several errors of release 1.0.0.1.
From now on the document-type "iso" will be supported in the future 
releases.
Although release 1.0.0.1 was not widely circulated, if you have any
documents produced by that application and want to use them in the 
future, don't throw version 1.0.0.1 of the program away.
As stated, the backward-compatibility-maintenance starts with (this) 
version 1.1.
