Update CSS classnames

Up until version 1.4.2 of Chi, CSS classnames were based on Atomic Design methodology. Version 2.0 uses Chi specific classname prefixes instead of Atomic ones for consistency with Chi's web component names (e.g. a-icon is now chi-icon).

Level	Change
Atom	a-classname__extension`chi-classname__extension`
Molecule	m-classname__extension`chi-classname__extension`
Organism	o-classname__extension`chi-classname__extension`
Template	t-classname__extension`chi-classname__extension`
Page	p-classname__extension`chi-classname__extension`

In order to use Chi 2.0 it is necessary to update classnames that are currently in use in your project.

For Unix users
For Windows users

1. Download the replace.sh script from Chi's repository:

https://github.com/CenturyLinkCloud/ux-chi/tree/master/scripts/chi-classnames/bash

2. Place the Bash script in a folder together with your project to achieve this file structure:

/replacement_folder
    |── /project_folder
    |── replace.sh

3. Open replace.sh with IDE and change variable PROJECT_SRC with the path corresponding to your project folder:

PROJECT_SRC='project_folder'

4. Open terminal, go to the directory with replace.sh and assign necessary permissions to it:

$ chmod +x replace.sh

5. Launch replace.sh script:

$ ./replace.sh

6. Verify Atomic prefixes are correctly replaced.

1. Download replace.bat and classes.txt script from Chi repository:

https://github.com/CenturyLinkCloud/ux-chi/tree/master/scripts/chi-classnames/batch

2. Place both files in a folder together with your project to achieve this file structure:

/replacement_folder
    |── /project_folder
    |── classes.txt
    |── replace.bat

3. Open replace.bat with IDE and change variable PROJECT_SRC with the path corresponding to your project folder:

set "PROJECT_SRC=project_folder"

5. Launch replace.bat script ( doubleclick on the file )

6. Make sure that Atomic prefixes are correctly replaced
