fixing/completing petstore sample for 2.1.1

[leo leonid]

hi,

in the current version of the petstore sample the jxform part does not 
work.
If you signed in ad want to change your account informations get errors.

This can easily be fixed by removing action="petstore" attribute from 
<xf:form> in the following files:
petstore/view/jxforms/EditUserInformation.xml
petstore/view/jxforms/EditAccountInformation.xml
petstore/view/jxforms/EditProfileInformation.xml

Further the form can't acces the address fields. To fix this you have 
to rename address1 and address2 to addr1 and addr2 in the following 
files
petstore/view/jxforms/EditAccountInformation.xml
petstore/flow/PetStoreImpl.js

Other parts of the application are still pending, like the registration 
of new users. If there is an interest I can try to implement this.
