Archive: Allow selecting multiple files

[956MB]

What's new

Addresses #254

As discussed in that issue, this implements multiple file/folder selection in the Archive file browser. With some personal design choices for the list selection indicators that can be changed if needed.

• Files and folders in different locations can be selected and then actions done on them (Cut, Copy, Paste, Delete)
• A check is used to make sure the destination path is not a child of one of the selected files/folders, and an error dialog is shown if tried.
• List items in the browser have either a regular indicator [+] (for files or entire folders), or a number [2] to show the amount of selected files in a folder.
• The setting Interface > File Browser > Selection Indicator was added to change which character is used in the selected file indicator: +, * or -. (These can also be changed or more added.)
• When a folder has files selected inside it and shows a [3] indicator, the folder itself can be selected and all the files inside it are deselected and the folder shows a [+].
• Renaming a file while in select mode is also possible, but it works on one at a time. Not all the selected files.

Keybinds for the "select mode" are as follows:

• left: deselect
• right: select
• click OK: enter folder
• hold OK: opens Actions/Manage menus
• back: exit folder

This set of keybinds allows for selecting files and folders the same way and the ability to enter folders for its contents. as mentioned in the issue comments.

Couple of other things I'd thought of doing but haven't yet (TODO):

1. Make the Select "badge" text at the top of the status bar also show the amount of selected files, like this Select (4).
2. Add a scrollable list to the delete screen when theres more than one file being deleted. Gives you a second to see the files about to be deleted rather than "Delete 5 files?".

I updated the delete screen with a new file list widget. It's scrollable up/down but the files are obviously not select able with a cursor or anything. They're just there as a visual confirmation of what you're about to delete. Of course it's up to whoever in charge whether it should be in there of not, but I think it's helpful. Fills out the empty space too.
