ScoreEntry: Move Score_Entry to ScoreEntry

Protected access wants to talk with the page ScoreEntry.html so
move things around for that to work.
ScoreEntry: Add section number to match score sheet
ScoreEntry: Re-use form to speed processing

On tablet devices the initial build of the form is pretty slow.
With this change the form is reset after score submission to
avoid the start-up cost.
Adds Reset Form button to clear all selections (also used to reset
the form after submission).
Adds support for manual score entry mode as well.
ScoreEntry: Remove link to timer

Having quick access to the timer from the score entry page
doesn't seem necessary and clutters the header.
ScoreEntry: Remove link to timer
ScoreEntry: scroll to unanswered questions

Clicking on the message "You have unanswered questions" will
scroll the form to the section with unanswered questions.
Well, it will scroll on some browsers (IE, Chrome).
ScoreEntry: Use cached score_info

When putting together the HTML for the questions the code also
saves an array of the critical information. This array is now
used for all the functions that need to scan through questions
such as validate, defaults, reset, compute score, etc. Hopefully
this is faster than using the XML methods to extract the data
from the Data.xml object.
