setting English (American) layout in sec_mod_linux

[sinev-valentine]

Currently, the linux version does not implement key modifier handling. Since some English layouts contain characters entered by means of modifier, it is impossible to ensure correct password input on such layouts. Therefore, before entering the password, X-server must be switched to English (American) layout. OS and password entry window should display the specified layout as the current one.

In keychain install package the English (American) keyboard layout must be specified as dependencies.

In the linux version, the keyboard is disconnected from the X-server. Keystrokes are treated as password entry window events. That would not be differences in the processing of keys and display on the screen, it is need to provide an exclusive mode of the password entry window. The mouse cursor should not be go outside the form. Window activity should not be toggled.
