Implemented file upload progress to the frontend using XMLHttpRequests,
since fetch() doesn't offer this functionality right now. Bit of a
fragmented approach to requests in the codebase right now, but hope to
resolve this soon. Not styled at all either.
Also added some nifty commands to the Makefile for producing smaller
binaries using some compiler flags and upx, and requires upx to be
installed (make small and make small_pi).
Implemented file uploading for both the disk and Backblaze providers.
Also implements a UI element and frontend logic for doing so from the
frontend.
Disk will write directly to disk, while the Backblaze provider will
attempt to stream the file from memory directly to the POST body. This
could introduce some problems down the line, so caching to disk then
uploading in the background may need to be implemented. It also
performs the final upload using a goroutine so the end client can
continue on it's merry way.
Backblaze proved a bit tricky to do, and considering switching to using
a library for managing Backblaze going forward.
Started work on a new basic frontend, with some magic code from
@tomhodgins (Tom Hodgins) for templating and processing data, which was
the primary purpose for considering a full-fledged JavaScript
framework. Fairly simple right now, with minimal "bling", and seems
"functional enough". Might need to consider options for using less or
no JS down the line if there is demand.
As part of this frontend, actually implemented route logic for fetching
a sorted list of providers (might be worth investigating whether
storing this final result in memory is worth the performance to memory
trade-off).
Also fixed a bug where adding "/" to the end of a provider name without
a file path would result in a 404. This was addressed with some Regex
filtering on the path that should be able to handle that matching.
