Added a spinbox to Settings->General to configure the number of recent items ranging between 0 to 100
The feature is more helpful when the option of "Open new files in tabs" is enabled. This is especially applicable in research scenarios where 15-20 documents are commonly open in tabs. It is common to drag-drop several files onto the pdf reader such that they also open in new tabs, resulting in a more consistent history.
In case of multiple Okular instances, the last Okular to close, updates the history.
