Add ability to use custom Flag types
...
Users can now use custom flags types (conforming to the Flag interface)
in their applications. They can also use custom flags for the three
global flags (Help, Version, bash completion).

Make ApplyWithError a public method on errorableFlag

Return an error when parsing environment variables for values fails
...
Currently cli silently (aside from IntSlice and Int64Slice which oddly
printed directly to the error stream) ignores failures that occur when
parsing environment variables for their value for flags that define
environment variables. Instead, we should propogate up the error to the
user.
This is accomplished in a backwards compatible manner by adding a new,
internal, interface which defines an applyWithError function that all
flags here define. In v2, when we can modify the interface, we can drop
this secondary interface and modify `Apply` to return an error.

Consider empty environment variables as set
...
When assigning values to flags (also when interogatting via
`context.(Global)IsSet`.
For boolean flags, consider empty as `false`.
Using `syscall.Getenv` rather than `os.LookupEnv` in order to support
older Golang versions.

Add DefaultValue text for flags
...
Allows a user to override the default value of a flag in the displayed help output.
Ex:
```
cli.IntFlag{
Name: "foo, f",
DefaultText: "random foo",
Value: "bar",
}
```
Running `(app.name) -h` will now yield:
```
--foo value (default: "random foo")
```
Fixes : #504
