Don't update a visibility of the collapse_toolbar: if sidebar is collapsed and "show_collapse_button" doesn't have "true" value
+ Fixed typos in the Preferences.cpp
2. When "Search in English" is checked, then search in English names too.
3. Added score value at the end of option name -> [score_value]
4. Set focus to the Plater, when switch from some tab with focused field to the Plater and search window is shown.
5. For the mode, when settings are in non-modal dialog, neither dialog nor tabpanel doesn't receive wxEVT_KEY_UP event, when some field is selected.
So, like a workaround we check wxEVT_KEY_UP event for the Filed and switch between tabs if Ctrl+(1-4) was pressed
+ PreferencesDialog: fixed a control of the difference in layout modes
1. Fixed crash on OSX after change of the settings layout (PreferencesDialog should be destroyed before call of recreate_GUI)
2. Fixed dialog message during GUI recreation
3. In PreferencesDialog changed radio buttons view (under OSX they were bold)
4. slDlg mode - fixed switching between main frame and settings dialog (dialog->SetFocus() doesn't work under OSX, so we just hide it and show again)
1. PreferencesDialog: When "Cancel" is selected, don't close the PreferencesDialog, just revert layout mode selection
2. For the tooltip of "Switch to Settings" added information about shortcuts
3. Shortcuts for the switching between tabs work from Settings Dialog now
4. Fixed the collapse button show after preference's change
