from system/user bookmarks' name if possible.
Volume label on Windows was request from T46083, makes Blender more in line
with 'common' filebrowsing on this OS.
And now, we automatically set name of recent entries from the bookmarks, if path
can be found there, more consistent too from user PoV.
We need to use 'W' widechar variants of win funcs and convert wchar to utf8-encoded bytes
in those cases, sigh...
Note: theoritical fix only, need org reporter to test it...
Did not had any issue on linux, but looks like on some windows can slow things as Hell.
Or maybe just the presence of some network FS?
Anyway, not a good idea, so now fsmenu entries' valid status is stored and only evaluated
on startup (reading of bookmarks & co) and when opening file browser (refresh, like
for system bookmarks).
Bookmarks are now editable (i.e. you can rename them, and reorder them).
They are also listed in regular UILists, so you can filter/sort them as usual too.
Also, FileBrowser 'T' side area is changed to something similar to 3DView one,
in this case because we need op panel to remain at the bottom, and later because
we'll more than likely need tabs here!
Thanks to Campbell and Sergey for reviews.
Differential Revision: https://developer.blender.org/D1093
* Separated bookmarks managed by the OS (System Bookmarks) and bookmarks managed by Blender (Bookmarks).
* Added user pref to hide (or show) system bookmarks to allow users doing a video tutorial for example to hide their private system bookmarks
This feature should help especially MAC users who reported excessively long list of bookmarks which were added to Blender.
further fixes for 'RECENT' files panel in filebrowser:
* Also add the recent folder at the head if it is not yet in the list
* since we now insert at the head, we need to remove the skipping of the first entries if there are too many. Now correctly leaving the last elements unwritten.
* Another consequence of inserting at the head is that we don't want to reverse the list in the recent panel anymore - got rid of the corresponding code.
