Added new lables, syntax error fixes in README.md

[LeoNerdoG]

I have added some badges to the README.md file, so visitors can quickly see the project status.

Added badges are:

• Number. of open issues
• Number of open Pull requests
• Current license
• Latest release version
• Number of contributors
• Number of forks

Description of the solution adopted
No special descirption necessary, I just added the badge code into the README.md file and fixed some syntax errors in the file along the way.

Screenshot:

Any side note on the changes made
I have updated the "build" badges - one is now called "Jenkins build" and other one "Travis build".

Any thoughts or ideas from the community? Should we add other badges as well?
