Popup Window For Searching Dropdown List Item

[w3shaman]

Hey, I made some modification to FA. I made some dropdown list to have a link to open new window to search the items inside it. For the example the dropdown list of item, if the item is so many it wil be difficult for user to search them using select element only. It will be easier if we can search it in a popup window and the selected value can be automatically put on the select.
I also fix the insert.js because every links will be unresponsive after I navigate through opened windows using Alt + Tab
And the last one, I changed the database connection to use mysqli instead of mysql.
I hope there will be some other improvement that I can contribute.
Anyway, thanks for this great software :)

Thanks for your contributions. We will consider including the code in FA2.4 RC1
Keep in mind the main 2.4 git repo still resides on Sourceforge, the github one being mirror.

I just modify the manage item page to provide the link to open popup window for managing bill of materials when we updating manufactured item. I think it will be easier for user to manage it from one page.

When I want to edit the Invoice Deadline in delivery note, I got one row marked with comment "Marked items have insufficient quantities in stock as on day of delivery". It's true that the current item's quantity is not enough but the delivery has been done before and I just want to correct the Invoice Deadline.
I just modify this code:

if(is_array($q_class) && $new) {
    ....
}

It's working like I expected. But I just want to make sure is there any bad effect from it?
