The fixes to the following defects:
#28~#32

[done, resolved by fixing #30] /reports/showInvoice.php: The payment records of different sponsors are mixed together, possibly related to 26). However, this problem maybe related to the Yang’s local MySQL database. Yang will investigate tonight. See the screenshot below:

[done] /reports/showInvoice.php: change caption to “Sponsorship Summary - Last Payment Type Listed as”.
[done] /reports/reportDateAmt.php: button “View Invoice” has a hyperlink of “http://localhost/2014SponsorTestEnv/reports/showInvoice.php?vid=1997” where vid should be changed to sid. This defect results in errors on showInvoice.php later on because the page could not grab variable sid.
[done] /reports/showInvoice.php: remove hyperlink “View Registration History”, because this is for visitor registration and does not make sense to sponsors.
[done] /reports/invoiceList.php: the same issue as #30, in the hyperlink of “This One” that vid should be sid.
