- Temporary restored controls:
    1. "Move avatar lips when speaking" checkbox
    2. "Toggle speak on/off when I press:" checkbox
    3. "Push-to-Speak trigger" lineeditor
    4. "set_voice_hotkey_button" button
    5. "set_voice_middlemouse_button" button

They should be moved to the Sound&Media panel of floater Preferences. But the specification for the Sound&Media panel is not ready yet.
As specification will be ready, these controls will be moved to the Sound&Media panel.

- According to the specification deleted all controls except:
    1. "UI Size" slider
    2. "Show script errors in" radio group

- According to the specification:
    1. "Allow Multiple Viewer" checkbox
    2. "Show Grid Selection at login" checkbox
    3. "Show Advanced Manu" checkbox
    4. "Show Developer Menu" checkbox

STORM-583 ADDITIONAL_FIX Fixed top_pad of topmost control in "Colors" so that it is consistent with other preferences tab.

- Deleted Mouselook settings

- Increased vertical padding between "Cache size" and "Cache location" controls

STORM-582 FIXED Moved movement and camera control preferences from Advanced to the new Move & View tab.

In addition to moving existing controls, created stub checkbox and radiobuttons for double-click behavior. Logic will be hooked up to them in STORM-576.

- Increased vertical paddings between checkbox groups

- Changed label of IM checkbox group from "Logs:" to "Chat Logs:"

- Changed label of checkbox from "Add timestamp" to "Add timestamp to each line in chat log"

- Added checkbox "Add datestamp to log file name". For now this checkbox is not working, it's just a stub for a future functionality.

- Added descriptive text for the "Block List" button

- Decreased vertical padding between controls to insert radio group

- Added "Pressing letter keys:" radio group.

For now these radio buttons are not working, they are just a stub for a future functionality.

- Deleted color swatchers

- Repositioned rest controls according to the specification

- Copied "My effects" from General.
- Copied "Font colors" from Chat.
- Copied "Bubble Chat" color and opacity slider from Advanced.
- Fixed color swatches moved to this tab using attribute introduced in STORM-592 fix. Now only colored area is clickable.

Controls weren't removed from places they were before- it will be (or already was) done in "layout cleanup" subtasks of STORM-31.

- Adjusted vertical padding between all controls

- Set position and order of checkboxes between "Name tags" radio group and "Away timeout" checkbox according to the specification

- Deleted "My effects" color swatch

This height was uncustomizable even by explicitly changing height of textbox in xml (i.e. writing caption_text.height = "value"), because it anyway received hardcoded value in LLColorSwatchCtrl's constructor.

- Added new label_height optional attribute to color swatch and used it in code.

P.S. Removing unused space in all color swatches in viewer should be done in some separate issue.

- Moved checkbox "Bubble Chat" from Advanced to Chat panel of Preferences floater

Their panels are currently empty and will be filled in later tasks.

- Added checkbox to the floater Preferences->panel General to Enable\Disable UI Hints

STORM-284 FIXED Disabled "+" sign when user tries to drop a landmark to Favorites bar from any location besides My Inventory or Library.

* Bump CacheNumberOfRegionsForObjects up to 20k in the default settings.
* Make LLVOCache *actually* use this setting, with no upper bound.
