Merge lp:~zorba-coders/zorba/bug-1188058 into lp:zorba/system-module

[Chris Hillery]

Update non-core "system" module to Zorba 3.0 standards. Added system:all-properties() function.

[lp:~zorba-coders/zorba/bug-1188058]

37. By Luis Rodriguez Gonzalez on 2013-08-07

Changes for Zorba 3.0 done

38. By Luis Rodriguez Gonzalez on 2013-08-07

Forgot to add SystemModule::getKey()

[Luis Rodriguez Gonzalez (kuraru)]

review: Approve

[Chris Hillery (ceejatec)]

Looks very good, nice work. However, the moduleDocumentation test doesn't pass, so there must be a typo somewhere in the XQDoc. Also, I suspect once you fix that, it will complain that all those public variable declarations need to have XQDoc; you'll probably need to restore the doc from the old version. (%private variables, like errors codes, don't need XQDoc, but public ones do as far as I know.)

review: Needs Fixing
