Include description on how to install a released Circe.
lcs: Add third dash to header for package.el compatibility
elpa_tar: Typo fix.
build.sh: Add version to depended packages.
Updated version lines.

Circe v0.5 -> v1.0
lui v0.5 -> v1.0
lcs v1.0 -> v1.1
tracking v1.0 -> v1.1
Added "devel" to the version strings.
circe-fixes: Remove bugfix for minibuffer (included in 24.3)
lui-button-elisp-symbol: Use `help-xref-interned`.
tracking-ignored-buffers: allow function predicates
circe-lagmon-server-check: Handle circe-lagmon-server-lag being nil

That variable can be nil on an initial connection to the server,
which can result in lagmon raising an error. Handling it being
nil being basically the same as zero solves the problem.
