New accessors and methods

[tgirardi]

Adds Accessors for:

• Views
• Tags

Note: I have tested several methods for both accessors, but not all.

Adds the following methods:

• views.tickets (to request tickets from a certain view)
• tags.addTags (better to use the next methods...)
• tags.addTagsToTicket (appends new tags to a certain ticket)
• tags.addTagsToOrganization (appends new tags to a certain organization)
• tags.addTagsToUser (appends new tags to a certain user)

Could you add some tests for this?

@glrodasz yes. I'll try to do it this week
