New Features
Added settings for colors of arrows, shape borders and text
Now it is possible to change the color of arrows, shape borders and text:

When you change border or arrow color you can immediately apply new color to the text. When the color popover is visible, drag the top of the content area downward. You will see the switch control that enables applying new color to the text. By default this switch is enabled only for arrows if line and text color were the same when you opened interface with color properties. In other cases it is disabled when you open the interface.

Added settings for shape border types
Shapes now have 5 border options: no border, solid border and 3 dashed borders with different patterns:

Reworked text properties interface, added text alignment setting
In this version I reworked user interface for editing text properties. I put all text properties under one tab (including new interface for editing text color).

Added text alignment setting for shapes.

Added diagram settings for default colors and border type
Diagram settings interface now allows you to set default colors for arrows, shape border and text. You can also choose if shapes should have borders.


Also now when you apply new settings to existing diagrams you will have two options:
- Apply changes to existing diagram items
- Do not apply change to existing diagram items (New setting will be applied only to new items)
I removed the option that allowed to apply changes only to default items.

Added border and text properties to the interface for adding "Existing" shapes
Added border and text properties to the interface for choosing existing shape prototypes:

Minor changes and improvements
Slightly changed database shapes:

Increased text offset from shape borders from 1 to 4 pixels. New offset is applied only when you create new shape or edit an existing one. Your existing shapes will not be affected.
Enabled scrolling and zooming of the diagram while editing text.
Removed shape names.
Added menu that contains links to this Forums and new "About" window with copyright and app version information.
