meta: Modernize polybar

It turns out that merge commit messages are used to keep track of
branch information since the commits themselves only reference other
commits and the actual branches may be deleted at a future date (even
`git clone` by default will not pull in any other branches).

Personally, I find a meaningful commit message more useful than a merge
commit message, so I'll be using that instead. Later when looking at
the commit history, "Merge branch <branch_name>" will not be useful
since the mentioned branches will have already been deleted.

Some projects rebase all changes into one commit, then push that
single commit to master. This seems like a very convenient approach
for small fixes, although if done for larger changes, each individual
commit and its respective explanation is lost.

In particular, this merge commit adds a bunch of config changes that
make polybar (and the system itself) more practical to use. Borders and
gaps are now disabled by default, and can be manually set through bspc
for your ricing needs.
