Blender Git Loki

Organize Cancel/Execute buttons according to the OS standard:

Windows: Execute/Cancel
Mac: Cancel/Execute

Linux uses same order as the Mac in this case. That platform doesn't really have as strongly defined standards.

Swap icons for vertical and horizontal list views

These were wrongly used before

Clean up of header

Remove redundant controls, and rename Toolbar to Source List

Use simple action names in the File Browser.

Previously this was overly verbose.

- Open Blender File -> Open
- Save As Blender File > Save As

etc

Split Filter popover into Filter and Display

Filter contains options about *what* to show
Display contains options about *how* to show it

I used prop_with_popover for the Filter popover too to force it to show the disclosure triangle. Ideally this would not be needed.

Add context menu to File Browser

Keymap: Make File Browser keymap consistent:

- LMB Click to select
- Double-click to open
- Shift-click to select & fill
- Ctrl-click to extend selection
- Shift-drag to extend box
- Ctrl-drag to subtract box

RMB will be used for the context menu

Merge branch 'master' into filebrowser_redesign

Remove dead code

Now handled in Python.

Fix vertical list layout when thumnail view was active previously

Changed Displaytype to Vertical List and Horizontal List

Add new/changed settings to version patching

* Set flag to dynamically size file path region. Without this the region
can be resized, which is not wanted.
* Enable modification date/time and size details columns

Use full area width for filepath region

Also adjusts size for old files.

Fix crash with narrow file list rendering

Bring back active-default blue highlight for execute button

It marks the button representing the operation executed with enter.

Support toggling inverted sorting through column header (3 state)

Support inverted sorting

Adds a checkbox to the filter/display popup, to invert sorting. We do an
additional pass to reverse the listbase order, rather than modifying the
sort callbacks. That adds a overhead but guess it's not much of an
issue. The alternative would make return values a bit cryptic.

Fix background pattern not scrolling with view

Align modification date column to center, size to the right

Refactor drawing, use available with for name column

Makes drawing use padding sizes more correctly, removing need for
hardcoded alignment of elements. Since we now know the name column width
in advance, we can do drawing in order (not reversed).
