467449 - Tags should have friendly names and be normalized on backend

Status: NEW

Description

[Austin King [:ozten]]

For demo/prototype tags are fairly simple. For a more polished tagging feature we should do the following:

Friendly Tag names
* Add database support for a display_name column to tags table. This is presented to the user for specific uses of the tag. Example:
User#1 tags an reference 500 as 'Linux'. User#2 tags reference 501 as LINUX.
When we go to /references/tags/linux both 500 and 501 are listed. If we are on /reference/browse/500 then the tag is displayed as Linux.

* name - this column is the normalized tag name which is used throughout the system. Normalization should include lowercasing all characters and encoding non alpha numeric characters in some fashion.

* tags can be contained in quotation marks. Space is retained in display name and normalized in name field. Example "Windows XP"
