Synchronisation of app name (`SmartSystemMenu` or `Smart System Menu`)

[Korb]

README.md / README_RU.md / README_CN.md / README_KO.md — SmartSystemMenu
Smart System Menu detailed SRS document in greek.docx — Smart System Menu
SmartSystemMenu.exe' meta — SmartSystemMenu and Smart System Menu
Crush error message¹ — Smart System Menu

I believe that a decision should be made to use only one name.
