Refresh cached book information being shown in directories

Issue

Refresh cached book information being shown in directories after the popup menu is open for a random file.

Steps to reproduce

If you start fresh KOReader and hold any directory to show the popup menu, the options in the menu are the basic ones (Copy, Paste, Select...).

After you hold a book file to show the popup menu, if you try to show the popu menu in any directory (even the one with the row to return to the parent directory), a few more options are shown like Ignore cover, Ignore metadata and Refresh cached book information.

I don't frequently change covers. Today I changed a few mostly in the same directory. I can go one by one but it would be nice to refresh the cached book information for whole directories.

Look at the Plus button (upper right) menu - Extract and cache book information.

We can also think about the new button "Refresh cached books information" for selected files.

Extract and cache book information works, many thanks. It does not seem to refresh the covers that are currently shown but if you refresh they come.

Refresh cached books information for selected books would be also nice, but definitely enough with doing it for the whole directory + subdirectories.
