Fix bin/run

This was referring to a file we renamed and it did not use GODEP path
Fixing shebang!
Improve README instructions for forking and development

[Finishes #70686778]
Ignore tags files

ctags is where its at
Add a 'cf config' command

Currently only allows setting the timeout for async requests to Cloud
Controller, but we anticipate adding more soon.

[Finishes #70242276]
Add config --trace flag

[Finishes #68903318]
'cf config' accepts a --color flag

[Finishes #68903282]
Make logic in colors package more clear

Instead of double negating conditions we should try to express what the
state will be.
Add a hook for setting color from the config

[#71045474]
Change color enabled to a string

This is a bit of hack. We needed a ternary value because we need to capture
whether the user ENABLED it, DISABLED it, or did neither

[#71045474]
Uses --color value to enable/disable/ignore coloring

[Finishes #71045474]
Trace should also respect the user config setting

[Finishes #71045364]
Gateway respects user-defined Async timeoutj

[Finishes #71039042]
Fix create-buildpack from local directory

[Finishes #70766292]
Add more instructions for first time checkout

We removed the instructions for godep. Upon further reflection, we
didn't want to duplicate their instructions in case they change in the
future.

Added a note that you can safely ignore a warning when 'go get'ing the
cli. This warning is caused by the cli not having any .go files at the
root.

Added instructions to cd to the directory for the cli before adding a
remote. I, Tim Jarratt, had assumed that people would know how to do
this, but I think it's helpful to provide a little more context to
people coming to this for the first time.

[Finishes #70686778]
Spiff up our bump-version script

We are thinking about additional steps we need to do after bumping the version and
releasing a new version of the CLI. This message ... seemed prudent.
Change links to stable and edge builds

We now use The CLAW as a stable source of links to stable and edge
builds.
This is an advantage over direct linking to S3 because

1. It's easier to update
2. It's less obscure than changing metadata for zero byte files
3. We can share the details of how this works with the community
4. It's easier to understand

ALL HAIL THE CLAW

[Finishes #70725858]
Refactor cf env to not use an application requirement

Probably seemed like a good idea at the time, but we are about to change how
the environment is retrieved from Cloud Controller, and making this change
will make it easier for us to do that.
Bump loggregator_consumer

[Finishes #71250896]
Fix a silly bug in buffering logs

We intended for this to default to 5 seconds. 5 nanoseconds is ...
not nearly long enough.

Huge shoutout to @msykes and @fraenkel for bringing this to our attention.
