Develop. This changes improve compatibility between MServer and WebKit and the Chrominium embeded framework

What it includes is:

1.- A string including version information on the server GUI when the server launches. It was missing so any version could look the same as any other one.

2.- It includes a function called WriteDataType that just adds the Data-Type "line" to an HTTP header being sent

3- I've also included the calls to WriteDataType on every http header construction

This minor changes allow samples to run on WebKit and the Chrominium Embeded Framework.
