Urgent a bit: Fixing the message about KDevelop on twitter/facebook/else

Hi,

thanks to whoever did it for mentioning the 20th anniversary on Social Media. 
We KDevelop contributors sadly had no time to do a proper promo thing about 
this, needing all resources currently to get the 5.3 Beta and then the 5.3 
finally done. So that blog post of mine was just a quick dump to have any 
mention at all in the blog-o-sphere.

Just, the text currently used is screwing the messaging around KDevelop to a 
good degree. KDevelop's mission is not to be only for software development 
done in the KDE community, but by anyone.

Citing kdevelop.org:
"KDevelop is a feature-full, plugin extensible IDE for C/C++ and many other 
programming languages. Supported platforms include Linux, Solaris, FreeBSD, 
macOS and other Unix flavors as well as Microsoft Windows."

So please change the text e.g. to 
"KDevelop, the development environment that helps you build good software"

Fixes also the fact that there is more software than just "applications" and 
which can be developed using KDevelop.

Cheers
Friedrich
