STORM-263 FIXED popup menu of Cog button in lower-left of sidebar panel closing on second click

- Changed type of gear menu buttons from LLButton to LLMenuButton in all sidebar panels where gear menu button is used.

- Added setMenuPosition(), setMenu() and updateMenuOrigin() to the LLMenuButton.

- Moved actions common for displaying a context menu to LLMenuButton::toggleMenu().

- In all sidebar panels where LLButton was replaced with LLMenuButton the following steps were taken:
    1. setting gearMenu and its position relative to the menuButton with LLMenuButton::setMenu()
    2. setting mouse down callback for the menuButton if needed.
    3. calculating the menu origin point with LLMenuButton::updateMenuOrigin() in mouse down callback
