remove unused code.xml files

these files were used to validate and parse
code.xml files in catrobatlanguageversion 0.3.
the format is not valid any more
add XStream aliases

* remove package name from xml
* all fields start with lowercase character
add uploadTest

the webserver filter out projects with
catrobatLanguageVersion codes that are
not supported any more.
this test tries to upload a program with an
older languageversion number - an errormessage
should be displayed
fix responseCode check when uploading

* if responseCode != 200 - display errortoast
* fix uitest Reflection
remove alias for Look.class

class is not serialized - no XStream alias needed
temporarily remove uploadtest

* upload of projects with japanese projectname does not
work (it worked in the past because we didn't check the
resultcode from web...)
