Additional changes for commit 999f81951c14 - necessary changes for files in /en/ directory in order to make files properly localizable
Also, removing some found duplicates in notifications.xml

MAINT-4127: New default mode when clicking links: Linden links open in viewer, third-party links open in user's browser

Fixed the "Use external browser" radio group to work with its setting properly:
* Specified valid boolean values ("true" and "") for the radio buttons.
* Made default value of the setting boolean to ensure proper initialization.

STORM-1482 The Viewer shouldn't overwrite the crash behavior settings, some cleanups to the crash reporters, and the ability to use --set GroupName.SettingName to set parameters outside of the (default) Global settings group.

Renamed llsocks5.cpp to llproxy.cpp.

Implemented improved cache control user interface, changes approved by wolf.
* Moved viewer cache controls from the setup preference panel to advanced
* Changed cache size control slider into a spinner
* Readded a clear cache button along with a cache clear confirmation dialog
* Renamed the reset button to "Default Location" to clarify its function

 * Changed the hard coded cache limit in llappviewer.cpp to 10GB as well as the
   slider maximum in the preferences menu. * The VFS cache is capped at 1GB due
   to file system limitations. The former 80/20 split between texture/vfs is
   maintained up to 5GB. Above this limit the texture cache is given all
   the additional cache space up to 10GB.
 * Fixed a log message in lltexturecache.cpp that was not showing the correct
   texture size. ER-883
 * Fixed a bug in llfloaterpreference.cpp that caused new cache value to be
   written to the old cache setting. This resulted in the the cache not being
   cleared when the location was set back to the default. ER-882
 * Disabled the "The cache will be cleared on reboot" message that is triggered
   by the reset button in the cache preferences in the case where the cache
   is already located in the default location.  The cache is only cleared when
   its location is changed. This is intended to address resident confusion
   regarding the purpose of the reset button, as demonstrated in VWR-19562.

change updater settings from check box to drop down menu; add choice of whether to install automatically as well as download automatically (not actually implemented yet).

- Deleted Mouselook settings

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

DN-120 "As a Viewer Developer, I want to update general preferences, so that "Show Display Names" appears less intrusive"
DN-160 View Display Names Preference extends below border in preference

Changes:
- The line editor is now scrollable.
- Its value is duplicated in the tool-tip.

Technical notes:
If you set the "enabled" param of a line editor to "false", that will disable text selection in the widget.
However, if a line editor is initially enabled and then gets disabled with setEnabled(FALSE), it will remain selectable.
It looks like bug, but I'm not going to fix it now to not introduce issues like this one.
Instead, I'm applying to workaround which is to enable the widget initially and disable later, thus keeping it read-only but selectable.

popup blocking notifications now handled in all web_browser instances, not just llfloatermediabrowser
