Unification of input style for phone number. Now every time when the user will provide
a phone number in gui the right function key (RF key) will be work as CLEAR.
This means that if any number is in the phone number field, the RF key will remove
the last character. Otherwise it'll work as typical BACK button.
This changes also provide ability to add * and # sign to number.
Updated widgets margins. Updated used fonts. Updated focus
change bold on font, cursor position, underline bold. Added
line spacing support and cleaned underline properties.
Due to vfs deprecation there is need to remove all vfs calls from code. This PR covers module gui. There are some modifications in other modules included which are necessary because of build system issues.
Change filename of internationalization files from i18 to i18n.
I18n should stand for internationalization, not i18. That's why I changed in 'module-utils' name of the folder 'i18' and both .cpp and .hpp files to 'i18n'.
