1st attempt at handling a form POST event

- managed to add an upload.js which fires an ajax based POST request to
the webserver
- the webserver manages to capture the JSON content (title, description
and price) and prints to the screen + appends to the buy section!

problems
- seems that the stack keeps growing as when you hit refresh the page
fails multiple times ?!
- also there is an error when submitting the page!?
Handling transition from SELL to SELL SUMMARY page

problems:
 - don't dynamically render data from the SELL screen onto the summary
screen
 - I keep appending to the end so going back and forwards causing the
BLAH data to grow
 - I haven't yet performed the real GET request to the server to submit
the data
