Update initEnvironment.sh and cli_printMessage:
- Remove centos-art.sh personal information.
The copyright information is used by `render' functionality and
`about' functionality. Inside `render' functionality we use the
function cli_getCopyrightInfo and inside `about' functionality
we use the file copying.txt to show both the copyright
information and the license under which centos-art.sh script is
released.
The cli name (CLINAME) variable is used by cli_printMessage to
print AsErrorLines. Since this is its only use, I removed the
CLINAME variable definition from initEnvironment and started to
use the `centos-art' string inside cli_printMessage function
instead.
The version (CLIVERSION) and description (CLIDESCRIP) are not
used, so they were removed saftly.
