Added new attribute image_flash to button.xml which sets an image used for button icon when button is flashing.
Pointer to this image is stored in member mImageFlash from LLButton and is used in LLButton::draw(). There are two
ways an image can flash now - by making changes in color according to flash_color attribute or by changing icon from
current to the one specified in image_flash. Second way is used only if the name of flash icon is different from
"FlashIconAbsent" which is there by default. First way is used otherwise. Used new selfmade orange icons for
flashing tabs.

EXT-7198, EXT-7491 FIXED Added mutli-selection support for outfit items and outfit tabs selection support.
- Added selecting multiple items from more than one accordion tab.
- Integrated context menus from Vadim's patch for EXT-6726 Appearance SP menus (WIP tier 2).
- Added selection to accordion control to use it instead of accordion tab focus in cases when focus is lost and outfit tab should stay selected.
- Changed "Wear" button behavior: "Wear" puts on currently selected outfit (as the tooltip reads "Wear selected outfit"). There is always an  outfit selected when the accordion is focused so for now there are no cases when only some items are selected. Separate items can be worn from context menu.
- Added moving accordion tab selection with right click. Fixed (EXT-7491) Right click on an accordion title should move selection to it.

killed accessing the asset server for map textures after http returns 404.

Code cleanup.
Some minor changes in logic for when low res texture is used.
Added more metrics to notifications and texture debug output.

Added a check for visibility changes that should prevent users from getting
"stuck" in appearance editing mode by closing the appearance editor
prematurely (clicking sidebar hide, etc).

Camera state should be restored when panel is restored.
