Linearise file uploads using an explicit queue

As a continuation on #54:

I still want to linearise the uploads

[merforga]

Is it possible to do this:

Add following text below to the page.

Use this screen to upload your logs for analysing. To upload your logs, simply drag and drop them into the area below. GW2 Raidar supports both .evtc and .evtc.zip formats from ARCDPS.

While they're being uploaded, you can continue to browse around the website. Click on any log file marked green to view the results

Note that refreshing or closing the page will cancel any pending uploads.

Done I think

Looks like subsequent files get stuck after initial queue is finished. To replicate, upload 1 file. When finished, try uploading more. It gets stuck. Adding more files while there's a queue still works as intended.

Thanks. Done I think

Amazeballs!
