Support for multi-char-separators in CSV

This change requires that the following patch is applied to OpenCSV:

http://sourceforge.net/tracker/index.php?func=detail&aid=3599477&group_id=148905&atid=773543
Added CSV quote options

Added two additional CSV options, one for parsing and one for export.

Specifying strict quotes when parsing will ignore all data not quoted.
Specifying quote all when exporting will enclose all values in quotes.

No front-end changes made, just added the support for the options in the
requests.
Quotes should not be removed from values

Leading quotation marks should not be removed from values. If they have
been left by the importing parser they should be considered part of the
value.
Fixed history and header update in IE

Due to Internet Explorer caching GET requests the Undo/Redo list and
column headers were not updated, leaving essential parts of the user
interface crippled even if Google Frame is installed. Adding
Cache-Control headers to the responses fixes this.
Fixed removal of upload temp files

Fixed an issue with an unclosed stream preventing upload temp files from
being removed after use. Also removed the use of FileCleaningTracker and
instead added manual removal of all tempfiles. By doing this the reaper
threads in FileCleaningTracker are avoided and files are removed
directly after use.
