#3 Approval determined from Group instead of Category

[Kenneth Buch]

I'm installing ExtCalendar2 for the first time and was
running it through some tests to see if it would work
for my situation. I wanted users to be able to register
themselves but didn't want all users to be able to post
events to the calendar. So, I wanted two different
groups, both without any extra privileges, where one
could post without requiring approval and the other
would require approval. I couldn't figure out how to
set this up so I modified the code.

The attached patch does the following:

1) Adds a new setting -- "Determine approval by
settings for" with valid values of "Group" and "Category".

2) If "Category" is selected, the code runs as is.

3) If "Group" is selected, the upl_need_approval field
for the user's group is checked to determine whether
approval is required.\

I only made changes for lang/english.php.

I also want to disable Picture Uploads as I don't want
a directory with world-writable permissions but I
haven't figured that one out yet.
