Wrong wordings in field implementations

There are two more incorrect wordings and some improvable ones in the field implementations for book, comment, search and user:

Search: Links from

The helptext "Nodes that link from the node." makes absolutely no sense. Suggestion: "Other nodes that are linked from the node."

Search: Links to

Add the word "other to the helptext, so it reads: "Other nodes that link to the node."

Users: E-mail

"This field is not normally shown to users" wold mean it is displayed differently. What was meant it indeed: "This field is normally not shown to users"

Book: Menu links

In the help text "The order of pages in the book hierarchy. Remember to sort by weight too if you want exactly the right order." the commata around "too" are missing which makes the text a bit hard to read. My suggestion: 'The order of pages in the book hierarchy. If you want the exactly right order, remember to sort by weight, too.'

Comment: Name

Help text: "The name of the poster." Elsewhere you use the wording "comment's author", using it here as well, would be consistent. Also added a note that the name can be rendered as a link to the author's homepage.

Comment: Homepage

Help text. "Can be a link." is a bit confusing, "Can be rendered as a link." should be more clear.

Also, "Will be empty if posted by a registered user." is a bit confusing, because registered users don't post their website address in comments. "Will be empty if the author is a registered user." should be slightly better.

Removed the sentence "The homepage can also be linked with the Name field." I understand that you wanted to point the admin to the 'Comment: Name' field, but it is completely confusing. We'd better add this information to the 'Comment: Name' helptext (as above).

Rolled everything into the enclosed patch.
