Add a few missing NEWS entries
Force selection to change when Default or Alt colourscheme chosen

The selection foreground and background are not changed unless
the respective 3rd or 4th field is true (see highlighting.c:790).
Suggest to provide git-formatted patches rather than `git diff` ones
Update of po-files for string freeze for upcoming 1.22 release
Merge branch 'frlan/svn_cleanup'
Fix verbose output with GLib 2.32 and newer

Since GLib 2.32, messages logged with levels INFO and DEBUG aren't
output by the default log handler unless the G_MESSAGES_DEBUG
environment variable contains the domain of the message or is set to
the special value "all".

Since we use INFO level messages for verbose mode, we need to make
sure this environment variable is properly set when in verbose mode.
Display warnings, critical and error messages even if not in verbose mode
Remove an useless NULL check and error message

gtk_builder_new() cannot fail but in case of memory exhaustion, where
the GLib allocator will abort anyway.
Enable two strings for translation. Patch by gymka
Update po files after enabling more strings to be translatable.
Update of Lithuanian translation
Fix applying default selection colors after editing 'selection' style

Default colors were not restored when disabling the override flags.

Add workaround for users with an invisible selection style

This is likely to be the case for any users that copied the system
selection style line as this was incorrectly set before, but not
applied.
Adding a small note pointing out that setting a default keybinding might not the best idea for plugin maintainers
Do not suppress warnings (Windows makefiles)

Also do not define G_OS_WIN32.
Fix using CXX, CC as usual to prevent override problems (Windows build)
Update of Spanish translation
