update nopcommerce

update nopcommerce from 3.3-3.9
Here is the steps to update

download form nop
unblock the zar for window securtiy issue,if not, there wil be problems when releasing
Extract files
setup by: run NopCommerce.sln, clean and rebuild
view in chrome
you will see the installation page: input your local database and choose to create one database, it doesn’t matter, because you will rewrite it later, but it seems that you cannot skip the initial part
open nop.web/app_data/setting.txt
change the database to your own one. make sure the version of you database is same with the source code. if it is not ,you should download the update.sql from nopcommerce and run it one by one: 3.3-3.4, 3.4-3.5. when you run it, make sure you open the microsoft sql server and click the target database you want to update
copy the original theme from v3.3 to 3.9, choose the new theme from backend of website, then you will notice the difference ,what we are supposed to do is address them one by one:
