Move Utilities class to utils.py

[ivanhercaz]

Make an independent file for the Utilities class (utils.py). Tasks to do:

• [x] Migrate the code to utils.py.
• [x] Simplify the use of the class in bot.py deleting the repeated u = Utilities() to something like:

  
  import utils as u

def removeFullStop(edit):

Code

fsc.checkDesc(query, edit)

if name == 'main':

Code

After the projects prompt

edit = u.editMode()

Before the available tasks prompt

Then, in the specific task it pass edit as an argument:

removeFullStop(edit)

- [x] Update the calls to the Utilities class after the replacement of `u = bot.Utilities()` in `fullstopschecker.py` by `import utils as u`.
