Issue Description

It should be easy to specify that parts of my prompt (e.g. the path) are in bold. In some consoles like http://github.com/jwilm/alacritty - bold looks really nice.

I noticed CustomAnsi is an option and it works, but it is less friendly.

For some motivation, Here is a side by side comparison of the differences:

The left side (11-15) is conhost, the right side (39-42) shows alacritty as well as the settings. Both windows are using roughly the same font (Fira Code, but different sizes - as similar as I could make it look.)

At any rate, the point is that bold might not be that interesting for conhost, but it is definitely interesting for other consoles.

We are actually in the process of dropping CustomAnsi and allowing you to specify VT seqs in the Text, FG and BG fields e.g..:

$GitPromptSettings.DefaultPromptPath.ForegroundColor = "`e[1;96m"

Or you could do this:

$GitPromptSettings.DefaultPromptPath.Text = "`e[1;96m" + $GitPromptSettings.DefaultPromptPath.Text

It felt more flexible to allow putting VT seqs in the Text field as this gives you even more color control:

function Test-Administrator { $true }

$GitPromptSettings.DefaultPromptPrefix.Text =
    "`$(if (global:Test-Administrator) {`"$([char]27)[37m^`"})" +
    "$([char]27)[33m`${env:USERNAME}@$([char]27)[95m`${env:COMPUTERNAME}$([char]27)[90m:" +
    "$([char]27)[94m`$(Get-PromptPath)$([char]27)[90m:" +
    "$([char]27)[35m`$(Get-Date -Format `"d-MMM HH:mm:ss`")$([char]27)[90m:"

Ah, that's the reasoning I used in PSReadLine colors too - dropping the Foreground/Background options.

Feel free to close, just make sure to call out the breaking change between beta releases because at you now know at least 1 person is using CustomAnsi.

It would be interesting to have a PowerShell module for constructing VT sequences (e.g. chalk), rather than add more formatting smarts to posh-git.

I'm going to go ahead and close this, since #616 (removing CustomAnsi) would compose well with such a helper.
