Quite a huge new update for AutoUi!  I'm personally very excited about this one, as there are tons of life improvements and new features.

NEW ELEMENTS

• auto_button
  • A simple sprite with text aligned to the center/left/right 
  • Includes built-in mouse functionality and index changing for checked, unchecked, highlight, etc. similar to the checkbox    
• auto_row
  • A row which arranges child element arrays into left, center, and right sections with custom padding and spacing.
  • (NOTE: ONLY fits inside v_containers)

NEW FEATURES

• '.add_watcher(_obj, _var_name, _func_call, [_func_params])' available to all elements
  • Similar to signals, watchers check an obj/struct variable for a change, and if that change is found
  • it calls the user function set using add_watcher()

  label.add_watcher(o_player, "hp", function(_new_value, _maxhp, _color) {      set_text(string_concat(_new_value, "/", _maxhp);      color = _color              }, [maxhp, c_red]);

• Added o_07_watchers example object
• Added o_08_rows example object

UPDATES    

• All constructor user methods (ie on_click_func, on_hovering_func, on_value_changed_func etc.) now have an additional <>_args variable
  • They also have their own creation methods (eg. <element>.set_click(_func, _args), <element>.set_on_hovering(_func, _args), etc.)

label.set_click(function(_a, _b){ _a.variable = _b; }, my_a_var, my_b_var]);

• New container methods 'get_hpadding' / 'get_vpadding'
• New '.add(_element)' method for auto_containers that take either an element or array of elements
• New '.set_sprite(_sprite,[_index=0])' method for auto_image
• New '.align_right', '.align_center', '.align_bottom', etc. methods for ALL elements
• New '.set_max_segments' for Segmented Lifebar
• Added 'uvals' variable that references user_values (shorthand for easier code legibility)    
• 'play_one_shot_animation()' is now available on every element instead of just containers
• Added additional helper methods for images and scrollers (mainly for v/h alignment; auto_image_right(), auto_image_bottom(), etc.)
• INTERNAL: Signals and watchers are now calculated BEFORE the step() method of each element is called

ALTERING CHANGES

• Added a +1px y offset to labels that are either vertically centered in a h_container, or in a v_container
• IMPORTANT signals no longer allow function calls
  • If you're using them , just change ".connect_signal_<>" with add_watcher() (see above in new features)

BUG FIXES

• Default value of separation on auto_label helpers is now set to 8 (was 9999999999...?)
• auto_lifebar's initial value was defaulted to 100; is now undefined (which will just set it to max)
• Checkboxes now no longer alter sprite color if text color is changed
• Default value for lifebar is now undefined which will set it to your max value if not set
• Image set_sprite_settings method had a wrong function call
• Calculation of aui_get_gui_x/y was incorrect - should fix any hovering issues.
• 'show_debug_outline' set to true now highlights white if hovering
