Allow For Adding More Than Word As a task

[Jagoum]

Right now the program can only add a single program as a word
Add a method that can allow the user to put multiple words to describe his task comfortably.

Hi, I have added support for longer task strings, after the command, I have assumed that all the rest of the space seperated words are a part of the task string and they are concatenated into one string. Hope that solves the issue, do let me know if there is anything else.

Thanks!!
