Small bugs in 3.1

1. Header in Dashboard widget is printed twice.

Problem is in file inc/tabledata.php, line 34

echo $tabletoshow .= $header;

should be changed to:

$tabletoshow .= $header;

2. Wrong/old textdomain used in some files:

Replace 'WPEC' with 'wp-email-capture'

inc/pagedresults.php
inc/widget.php

3. Extra chars like CR and/or LF after php closing tag ?> in some files. Can cause “Headers already sent” php error. More about this problem here: http://hardcorewp.com/2013/always-omit-closing-php-tags-in-wordpress-plugins/

4. Unnecessary files for old textdomain in languages/WPEC-xx_XX..
