14.1.0 - Some improvements in various functions

Upgrades in release v.:14.1.0 :

• input() function now allows spaces in input fields ( = unlike other special characters, the space is no longer preceded by a backslash ).

E.g.:
before version 14.1.0: input 1 "foo" "mam*ma mia" => "mam\*ma\ mia" ;
since v.14.1.0: input 1 "foo" "mam*ma mia" => "mam\*ma mia"

• notify_message()

1. supports a new option: -s|--seconds
   E.g.:
   since v.14.1.0: notify_message --seconds 10 "foo" ; notify_message -s 1 "bar"

2. will check icon provided if you use option "-i|--icon"
   since v.14.1.0: notify_message --icon "system" ; notify_message -i "/foo/bar.png"
   EBG checks if icon exists, otherwise ignores it.

• removed some superfluous alerts
