Add best practice guide for using bash aliasing to make shorter commands

[djgroen]

I personally use bash aliases to shorten fabsim eagle_hidalgo to feh, which really saves on typing individual commands, and using the toolkit.

In fact I think it's so useful that it may be worth inserting that in the documentation somewhere.

I don't know what place is appropriate for that currently though, perhaps we could make a best practices in automation guide in the docs section?

Hi @djgroen
I made the first prototype for this functionality, github branch : bash_aliasing
usage :
fabsim <machine_name> bash_alias:<alias_name>

since that the user added /FaSim3/bin folder to the .bashrc file, so by reloading that file source ~/.bashrc or restarting the shell, the new command should be available to be used

[djgroen]

@arabnejad Very interesting. Could you add a simple example to the docs on how to use this aliasing?

[djgroen]

Renamed bash_alias to bash_machine_alias to avoid confusion. Also added a check to avoid overwriting the fabsim command.

See commit 97e0a55

And I added documentation, so this is all done and dusted now.
