By separating scheme and port at the parser, we are able to set the port appropriately and also keep the semantics of the scheme being specified by the user later on. The parser also stores an address' original input. Also, the config refactor makes it possible to partially load a config - valuable for determining which ones will need Let's Encrypt integration turned on during a restart.

copy edit to wrap around 80 chars

not all lines wrap at 80 characters but now most do.

rewrite: Use middleware.Replacer for simple rule

proxy: Two small websocket fixes

browse: allow consecutive spaces in the header

Add a few super minor lint fixes

Hosts which are eligible for automatic HTTPS have default port "https" but other hosts (wildcards, loopback, etc.) have the default port 2015. The default host of empty string should be more IPv6-compatible.

proxy: make http header block scoped

proxy: make tests workable when offline

Instead of accessing the google website, we setup a local server
for test, then tests will work fine even we are offline.

proxy: 'except' property to ignore subpaths

parser: Allow use of environment variables in tokens

It no longer uses regular expressions.
It supports both the Unix `{$ENV_VAR}` _and_ the Windows `{%ENV_VAR%}`
syntax.
Added test for both Unix and Windows env. syntax.

Go programs using the caddy package may not want the it to capture all the signals...
