added eclipse project nature
this branch will enable the use of user access manager with any
taxonomy, not only 'category'
changed use of $qpdb to use full functionality of the api (e.g. delete,
insert, update, prepare)
removed unnecessary white space
fixed errors in UserAccessManager.class
removed unnecessary white-space
added user access management for all taxonomies, not only category
filter get_terms has three arguments: terms, taxonomies, args -
taxonomies can be used to filter the terms
getTerm and showTerms not handles all cases, where the terms taxonomy is
the requested type
fixed _getTerm function, which was not properly checking access rights
all terms are stored under 'category' which is a little confusing, since
other taxonomies are called differently.. this needs to be cleaned at a
later point in time, for now - this is the easiest way
The disadvantage currently is, that group associations with terms are
stored on a term basis only. If an identical term is used for different
taxonomies, the group access will be identical. So each group needs to
be access rights for term-taxonomy combinations
corrected handling of custom post types, by hooking to
registered_post_types and adding them to the validObjects handling, when
they are queryable
the previous way did assume, that "get_post_types" returns all
post_types, but since the UamAccessHandler is constructed long before
the custom post types are registered, it could not add them properly
