First of all, thanks for this really nice tool!

I think I found an issue regarding "Resource share"

Reproduction:
1. navigate to https://www.boincstats.com/bam/host/
2. Select an how
3. click "Edit projects"
4. Check there is a project with "Project default" as "Resource share" (value = -1)
5. Navigate to https://www.boincstats.com/bam/projects
6. Edit this project resources to be something else than 100, for example set 50 or 150, save
7. Go to the BOINC Client and click on "Tools" > "Synchronization with BOINCstatsBAM!"

Issue:
Notice that the resource share is 100 (and not the defined value in step 6)

Expectation:
I would expect to see the defined value in set 6

Additional details:
Settings the resource share on the host page (with a value like 50 instead of -1) works correctly
