Checkbox-Plugin v1.0.3 breaks Opera-Compatibility

[GoogleCodeExporter]

What steps will reproduce the problem?
Using Opera-Browser and Checkbox-Plugin v1.0.3

What is the expected output? What do you see instead?
Checkboxes in the mail list.

What version of the product are you using? On what operating system?
RC 0.95 + checkbox plugin v1.0.3 + Opera v12 + PHP5.4

Please provide any additional information below.
I upgraded the plugin by plugin_manager and the latest "fix" for mobile 
devices, breaks the fix before, making checkboxes visible on "Opera" browser.

The check for mobile devices tests for USER_AGENT and a lot of short strings, 
it checks for "oper" there as well, my Opera v12 is no mobile device, but the 
plugin does think so, and removes the checkbox from the mail-list and also does 
not allow for column selection anymore.

Fixing this might be easy, just remove that check for "oper" in the mobile-test 
if it has no special use there . it works for me at least.

Thanks!
