Cleaned up HTML code in templates

[mbabaj]

I Cleaned up the Html code in the templates. Now the orgs and the nav bar are only in the base.html and all the other files extend from there, if a change needs to be done in the nav bar for example, you will have to do it only once, and it will apply in all the files. this makes it easier to make changes and the code is much easier to read since there is only the relevant code in each feature file. in about.html is only the "about code", in features.html is only the "features code" and so on.
let me know if there is any changes needed to be made
