Fura Code Powerline -> Fira Code for Powerline

Adding instruction for Fedora installation

Fedora or redhat based distributions installation instructions

Makes Font config section more simple and 
comprehensible as it is unintelligible to tell
while file, the reference 'this file' refers to.

Quick Installation does not need cloning the whole history of the repo, especially if they're going to delete the whole folder immediately.
So added ``--depth=1`` option to ``git clone``

Add "Profiles" to iTerm2 path. By default it's "General".

Should fix issue #193
Updates the non-italic font's version to 2.050

Add newly pushed font's info to list
