[Bibdesk-develop] CiteSeer support

[<tr...@vo...>]

As discussed in prior threads, I've figured out how to add basic CiteSeer
support to BibDesk. The changes are minimal, so I think it would be easier
to just list the necessary changes instead of post a patch file. If anyone
has questions, or perhaps some suggestions on how to make this patch
better (since I'm new to BibDesk and may have missed something or done
something wrong), please let me know. Anyway, here's what I did:

For the "Remote URL Fields" array *and* the "Shown Column Names" arrays of
Info.plist, I added:

    <string>Citeseerurl</string>

For the "Column Widths by Name" dictionary of Info.plist, I added:

    <key>Citeseerurl</key>
    <real>18</real>

In the setupTableColumns function of BibDocument.m, I added this after the
TinyFile clause:

    .
    .
    .
    }else if([colName isEqualToString:BDSKCiteSeerUrlString]){
        NSImage * citeSeerImage = [NSImage imageNamed:@"CiteSeer"];
        [(NSCell *)[tc headerCell] setImage:citeSeerImage];
    .
    .
    .

To BibPrefController.h, I added:

    extern NSString *BDSKCiteSeerUrlString;

To BibPrefController.m, I added:

    NSString *BDSKCiteSeerUrlString = @"Citeseerurl";

To the project's image resources, I added this file:
