Mariposa member card table

- Created Mariposa member card table
- Update get_member_info script so that it now syncs member cards
Beta release of member card support in IS4C

IS4C now supports member cards.

- It syncs with Fannie's memberCard table
- Member cards scan at the register
- If a member only belongs to one account, their member name and account
  are immediately brought up
- If a member belongs to more than one account, the cashier still needs
  to enter the account name, but the account search is restricted to
  only accounts that the member is a member of
- The "get member info" ruby script now successfully pulls the member
  card ID for the member
Removed debugging code from MemberCard.php
Removed very unnecessary line from reloadlanes.php
Scale now beeps when membership card is scanned.
Merge branch 'member_cards'
Initial commit for ajax callback to sync members and accounts
Rewrote function for syncing with individual MESS users and accounts

I rewrote the functionality for syncing with individual mess users
and accounts when a member and/or account is brought up at the
register.

The old way: ruby scripts that were executed syncronously. These
scripts could cause IS4C to hang when MESS was unresponsive.

The new way: an ajax callback that operates asynchronously and
updates the display with the member's balance, equity owed, etc.
when the callback returns.

I also updated BasicPage.php with a red/green dot to test if MESS
is online, which should help cashiers understand if the members
and accounts are properly being synced when the account is brought up.
Additional edit to BasicPage.php to support new MESS Online status
MemberCard scan now verifies whether or not member is active
Merge branch 'master' into errorfix
