Add additional text to guide user during file upload and output exploration

[mgro]

• Add 'Single-end FastQ File' and 'Paired-end FastQ File' as bold headers on the upload page next to the logos
• Add 'Click on the heatmap to explore drug resistance mutations' or something similar below or above the Resistance prediction heatmap

[mgro]

• we could also link to the Snakemake repo at the Bottom of the Predict page

[mgro]

• maybe explain abbreviations (FPR/FNR) in the prediction / output tab

I've fixed the first two, but the snakemake item is undefined. What is the predict page in this context?

The screenshots really helped here, I would have had no idea without them. Thanks!
