What's New in This Release:

# BACKEND

* (Windows) updated to 7z 9.17 beta

# CODE 
Updated units of Wolfgang Ehrhardt's crypto library

* Improved information reported by PeaLauncher, when applicable total and selected size of extraction operation reported separately 
* Improved indication of progress during long operation 
o if an operation exceeds 0.5 seconds it is shown a (simil)marquee progress bar 
o if an operation exceeds 0.5 seconds the refresh button is changed in stop button, allowing to stop current operation 
+ to prevent loss of time and user's focus a fresh instance of PeaZip is started in the last directory while the old instance is handled in background 
* Added PanelIntro, usually not visible due to the speed of a normal startup 
o if startup of the program is slowed for any reason user is informed about loading progress (0 inital form status 1 configuration and theming files loaded 2 input parameters parsed and executed) 
o controls cannot be clicked for error until GUI is fully loaded and ready to accept user's input 
o some controls load faster as they aren't visible 
* Improved file browser 
o Tighter integration with extraction interface 
+ New toolbar button on the right of "Extract", featuring a menu for 
# direct extraction of the whole archive (or selected archives) to most commonly used locations 
# check and modify most common extraction settings

(Ctrl+E or F12), "Extract all here" (Ctrl+Alt+E), "Extract all to Desktop" (Ctrl+Shift+E), "Extract all to Documents" (Ctrl+Alt+Shift+E); Ctrl+1..8 extract to bookmark's 1..8 path (if defined); Ctrl+9 extract to default output path (if defined). 
o Extraction from context menu made context sensitive, if no archive is selected the extract/test entries are disabled 
o Added small icons mode for file browser 
o Changed Toolbar modes: 3 with large and 3 with small icons (text below, text on the right, no text), and text only mode
