Added simple help description to the client CLI

[JohannesNicholas]

Hi,
This is my first pull request to this project.
Feel free to provide feedback or recommendations.

The following changes change the output help output of the command line.

Running python filesender.py --help currently will output:

usage: filesender.py [-h] [-v] [-i] [-p] [-s SUBJECT] [-m MESSAGE] [-g] [--threads THREADS] [--timeout TIMEOUT] [--retries RETRIES] -u USERNAME -a APIKEY -r RECIPIENTS files [files ...]

positional arguments:
  files                 path to file(s) to send

optional arguments:
  -h, --help            show this help message and exit
  -v, --verbose
  -i, --insecure
  -p, --progress
  -s SUBJECT, --subject SUBJECT
  -m MESSAGE, --message MESSAGE
  -g, --guest
  --threads THREADS
  --timeout TIMEOUT
  --retries RETRIES

required named arguments:
  -u USERNAME, --username USERNAME
  -a APIKEY, --apikey APIKEY
  -r RECIPIENTS, --recipients RECIPIENTS

With these changes, it outputs:

usage: filesender.py [-h] [-v] [-i] [-p] [-s SUBJECT] [-m MESSAGE] [-g] [--threads THREADS] [--timeout TIMEOUT] [--retries RETRIES] -u USERNAME -a APIKEY -r RECIPIENTS files [files ...]

A config file can be added to C:\Users\Joey/.filesender/filesender.py.ini to avoid having to specify username and apikey on the command line.

Example (Config file is present):
python filesender.py -r reciever@example.com file1.txt

Hi @JohannesNicholas,

You probably dont want to hard code the following as filesender exists on many other urls/institutes.

let base_url = 'https://cloudstor.aarnet.edu.au/sender'

Look at how this works https://github.com/filesender/filesender/blob/development/www/clidownload.php that fills in site specific values
