[rfc][icedtea-web][icedtea-web-1.5.2] allow also skip of permissions attribute check in case of disabled attributes check

[Jiri Vanek]

Hi!

The permission attribute is still incompletely implemented and mixed signatures apps are suffering not working with itw. by specifing it.

The implementation troubles ate in ITW two:
  - it can happen that application is loaded by various jnlpfiles
    => one jnlp file is signed, secondnot : however whole application is signed- so check in second jnlp file on sandbox attribute will finish by error.
    - fix it to have two kinds of attribute checkers - one jnlp file specific, and one global for whole app. Some attibutes are then checked globaly, some only on iven jnlpfile
  - the applictaion can be loaded by several classloaders each of them with differet permissions. This is real cause of issues with ^ and I do not know cure on it.


The reproducers are all jogam or joglor .... applets on http://icedtea.classpath.org/wiki/IcedTea-Web-Tests .

As for head - I'm working on oflfine integration of applets, and it is quite blocker. As for 1.5 jog* people have already reported this (got lost...) and we should make thi swork for them at least by this workarround.

J.

ok to head and 1.5?
