Configurable term link base path

Issue Summary

In my site, I've got a site map with each term linking to the table of titles of the corresponding nodes rather than to the taxonomy/term page. Each row in the table also contains other fields in addition to the node title -- e.g. 'updated time' etc.

For example:

Site menu

• Term A
• Term B
• Term C

term A links to the table of nodes:

Term A

| title of node1 | dd/mm/yyyy | ... |
| title of node2 | dd/mm/yyyy | ... |
| title of node3 | dd/mm/yyyy | ... |
...

To achieve this, I made a custom view, which is derived from the default taxonomy/term view. The custom view displays the table of the node titles instead of the node teasers.

I made a new field in the site menu settings page that allows the user to configure the base path to which the terms in the site map should link. Thus, I can set the base path so that instead of

taxonomy/term/[tid]

my terms can link to my custom view (or whatever I want):

taxonomy/titles/[tid]

I'm attaching the patch.
