* Move from deprecated wxScopedPtr to std::unique_ptr
wxScopedPtr was included previously through some header hierarchy which as of 3.3 is
no longer the case causing it to break. But instead of including a header for a deprecated
function explicitly, just move to std::unique_ptr as recommended by upstream.
* Convert to explicit conversions from wxString
As of 35c35c235e
wxWidgets defaults to STL classes, which has a side-effect that
some implicit conversions break. This patch converts those conversions
to explicit in anticipation of wxWidgets 3.3 release.
* Implement Language selection into settings
Initial commit to create a new tab in PreferencesNotebook for
Language selection. By default, if nothing is chosen, it uses the
current behaviour of using the language from system environment
variables. If another language is chosen from the settings, it is
saved into the Configuration.xml and this is used instead.
* Fix SetStringSelection() assert issue on macOS
* Add header include to fix build
* Add current language pack, authors and way to use literal strings
* Translations also for FreeBSD
* Minimal GTK3 WX build on FreeBSD requires wxGraphicsContext
* Get Preferences properly instead of workaround function
* Use WrapSizer instead of BoxSizer for author line
This forces long author lists to be put on a new line, reducing
the need to increase window width.
* Update Finnish translation
* Borrow translation from IDM_LANGUAGE where it makes sense
* Remove colon and thus unneeded function
* Simplify Language tab layout
* Reintroduce macOS specific fixes to Forms.cpp
* cleanup
* new xml Tag for en and de
* add linux support for env LANG
* precopiled header into TrueCrypt.fdp to substitute '_()' with 'LangString[]'
* more LangString in Code
* add Language xml's to Linux Setup location
* backup language for linux is en
* remove Language.en.xml install
* rearange new xml lines to end
* yes/no dialogs now translated
* All OK/Cancel Button now support international
