0.4.4 Alpha

• new command parsing (now you can execute multiple commands at once! The command separator is &//, but you can change it with the void function setCommandSeparator, which is located in the handlerCommands class)
• Updated two CMakeLists.txt files: added compilation flags for NRC and OS (O2, Wall and others).
• #pragma once removed in all .h files
• added currentUserData (variable type - user) to the userManager class
• new void function in Utils class - split... 💀
• new command - time (for (bad) measurement of command execution time)
• and something else, but I'm lazy
