Impovement: Replace ; with , in CSV file export

[andrej.pavlovic]

Version 1.3.4

CSV stands for comma-separated values. To be more Excel and other spreadsheet software friendly, please delimit the values in the CSV export with commas "," instead of semicolons ";". Excel is then going to open the file correctly without having to specify custom delimiters.

Changes required only in administrator\components\com_ckforms\controllers\ckdata.php file.
Replase all ";" and ';' with "," and you should be fine.
