Now your lambda or arrow can take over the role of the colon.

The SunOS CPU load check was returning with a comma, which would cause a
math operation to fail.

* Tried to use a more consistent and declarative voice throughout the
entire file.
* Moved an entry or two around to be closer to related features.
* Expanded the explanation of a few of the features.
* Made sure all comment lines fit in 80 characters (for no good reason)

Use parameter expansion power instead of sed.

On SunOS, cksum use tab as delimiter instead of space as on other
platforms.
Fix for #461

Because "declare -g" is only available since bash < 4.2

Regression introduced by d9cb55da.

Some users have a broken .bashrc that exports PROMPT_COMMAND. In this
configuration _lp_set_prompt is in PROMPT_COMMAND when liquidprompt starts so
prompt_on puts it in LP_OLD_PROMPT_COMMAND. This leads to a infinite
recursion as _lp_set_prompt runs $LP_OLD_PROMPT_COMMAND.

To work around those broken environments we now fix the environment by
unexporting PROMPT_COMMAND.

Fix bug introduced in 4636e0e1: battery level was not reported anymore on
MacOS X.

... for the analog clock feature.

Everything happens on master from now.

Time for a new release...

~/.liquidpromptrc is still the highest-priority, and
/etc/liquidpromptrc is still the lowest. A liquidpromptrc found
in XDG_CONFIG_HOME or XDG_CONFIG_DIRS, with their usual priority
order, are in between.

As requested on #427 we source exactly one configuration file,
the highest-priority one found: if ~/.liquidpromptrc or
XDG_CONFIG_DIRS/liquidpromptrc is found, we no longer use
/etc/liquidpromptrc. This is because a system-wide configuration
file in /etc might be incompatible with a newer locally-installed
version of liquidprompt.

One less condition when LP_ENABLE_VIRTUALENV=0 or neither VIRTUAL_ENV
and CONDA_DEFAULT_ENV are set.

Fixes #423
