lemmy: implement comment ModTime

lemmy, lemmy/fs: have comments as entries in post directories

lemmy: fix up, export comment path parsing for commands

lemmy: decode published, updated times Now that the Lemmy API returns nice timestamps, it's all done automatically by Go's JSON package.

lemmy: start decoding users in API responses This commit adds tests too as it's starting to get a bit trickier.

add Lemmy command for the acme text editor

Rework, move filesystem into its own package Major rework which keeps Stat, Read and ReadDir away from the filesystem tree and more to the file. The fs package implements extra functionality that doesn't really have anything to do with the core package. It also does not need to know how the core lemmy package is implemented to do anything, so may as well enforce the boundary explicitly.

start documentation!

Only cache communities in filesystem This keeps things simpler
