Change the code that strips "bridge" to work on a line-by-line basis.
Do not add a "bridge " prefix when displaying bridge configuration lines.
To reduce user confusion, turn off word wrap for the custom bridge textbox.
Improve alignment within bridge settings UI.
Windows: Increase width of Tor Network Settings wizard slightly so it is
  more likely that a bridge line with a fingerprint will fit.
Mac OS: Use a slightly smaller font within the custom bridge textbox.

To accommodate Tor Messenger/Tor Mail bundle packaging, use a path
relative to the current working directory when locating Tor files
(instead of relative to the profile directory).

Reorder wizardpage elements and fix associated logic.
Replace "proxy" with "local proxy" within prompts to help users distinguish
  bridges from proxies that are needed for local Internet access.
Reorder Network Settings dialog elements to match wizard order.
Remove unneeded label=" " from wizardpage elements.
Linux and Windows: Fix problem where prev/next buttons were displayed
  on first wizard page.

If the TOR_HIDE_BROWSER_LOGO environment variable is set, hide
Tor Browser logo within the network settings wizard. Based on
contributions from linostar and proper.

If the user sets a proxy but doesn't set a bridge, set ReachableAddresses
to include only ports 80 and 443.

Show a transient popup near the "Copy Tor Log To Clipboard" button after
is is clicked.  The popup panel fades away after 4 seconds and can also
be dismissed by clicking anywhere.

If a Tor error or warning message arrived while the Bridge Help was
open, the "Copy Tor Log To Clipboard" button was shown immediately
(instead of after the help was closed).

Improved alert/error messages and button labels.

Provide a stopgap solution:  route all tor messages captured by
Tor Launcher to the Browser Console.

If Tor Launcher started the tor process and it exits, display
a prompt that allows the user to restart tor.

Use 'make TL_LOGO=- ...' to build without a logo or
    'make TL_LOGO=path.png ...' to substitute a custom logo (115 x 80 pixels).

Update the logo that is displayed in the network settings wizard.

Increase the progress window width slightly and allow for three lines
in the description field.

This is a partial fix (network settings wizard only).
Also fixed a nuisance:  the torWarning CSS class was being added
  more than once to the "Copy Tor Log To Clipboard" button.

Remove 'si' locale files (locale has been removed from Transifex).

The problem has recurred for this file.

Account for new directory structure in getTorFile().
On Windows, prepend the directory that contains tor.exe to PATH.

When starting tor, pass the geoip6 file location (within the tor data dir)
via the GeoIPv6File command line config option.

Remove locales that have been removed from Transifex.

Fixed problem where the Proxy Type menu was not restored to the
configured value after restarting the browser.
