Usability enhancements

[trunkmaster]

Noteworthy changes are:

General

• All palettes and inspectors elements positioning, spacing were cleaned up and fixed.
• All palettes and inspectors autosizing was unified (centered) were appropriate.
• Made all NSTextFields (including NSForm) height unified.

GORM main menu:

• "Layout" renamed into "Format".
• "Font" submenu was added into "Format".
• "Group" and "Page Layout" were moved into "Format".
• Shortcuts 'p' and 'i' were removed from "Palletes..." and "Inspector..." because it's standard shortcuts for "Italic" and "Print" menu actions.

Palette

• Set window title from original window title of selected palette.
• Window titles were added/fixed for palettes.
• Selection icons represent selected section with background color.
• Arrow buttons were removed from scrollbar.

Inspector

• Inspector's shortcuts (Cmd+) are made available across application.
• Inspector window size increased if taller inspector was loaded. You can make Inspector window smaller only manually if visible inspector premits it.
• Apply changes the object only after TextField editing ends (Tab, Return was pressed). It prevents weird side effects for some objects' changes.

NSMatrix Inspector

• Additional section "Prototype" is created.
• "Match Prototype" button action was fixed: object cells are recreated using new prototype.
• "Prototype" box reflects changes that are made in "Prototype" section.

Connection Inspector

• Mark connected outlets with "dimple" image.
• Do not set document as edited if connection is failed for some reason.
• Removed redundant horizontal scroller from browser at top.

Window Attributes Inspector:

• "Autosave Name" form was moved into "Window Size Inspector".
• "Minwindow Icon Name": removed clear button, form converted into texfield.

Window Size Inspector:

• "Size" form was splitted into 2 forms to place them horizontally.
• "Size" group was renamed into "Frame".
• "Autosave Name" form was added and converted into textfield. NOTE: "Autosave Name" field is not saved into model file - is not encoded?
