Dynamic QR Code text limit much too small

[systemmonkey42]

Hi,

The default text / link size limit on dynamic QR codes is 100 bytes.

A simple route to a location in google maps produced a 210 byte url.

Since the URL does not need to fit into the QR code, this limit should be significantly increased.

Also, the error caused when a url exceeds the column size is fairly catastrophic.

• Application produces a crash screen showing mysql error message and internal diagnostic information.
• A file by the name of the QR code is generated regardless, meaning the code "name" can never be re-used without manual cleanup.

Thanks
