v0.1.3

telemaco 0.1.3

update refuses to replace cargo build output. A symlink from
~/.local/bin into a checkout used to be followed all the way to
target/release, where the next cargo build silently reverts the
downloaded binary. A directory named target counts as build output only
when a Cargo.toml sits beside it, so an ordinary install into a
directory of that name still updates.

Following a symlink is now reported before anything is replaced.

This is also the first release that can be updated from: 0.1.2 was the
first to carry the update command, so 0.1.2 to 0.1.3 is the first
version-to-version upgrade the path has ever been able to make.
