Change text for several buttons in the app

[dschioberg]

User feedback: Add the word engineer to the button developer. He was confused at what to do when looking for electrical engineers.

Remove the word Resume, replace with something else. Example: "more about you" in the headline and then a description like "write what you are looking for, what you would like to learn"

We can also add a field in which learners can describe an awesome project that they have done.
