Implement Brow.sh

[DavidSatimeWallin]

Brow.sh (https://www.brow.sh/) should be implemented as a shortcut. Would be nice to have a terminal browser in the basics.

The current (v0.6.0) version of vtm allows you to customize the tile manager profile by defining the VTM_PROFILE_N environment variable, N is any literal.

Example

VTM_PROFILE_4='"Browsh", "Browsh Browser Title", a("Term", "Browsh Window Title", "browsh")'

or instantly

export VTM_PROFILE_4='"Browsh", "Browsh Browser Title", a("Term", "Browsh Window Title", "browsh")'; vtm

Later I will make vtm menu items configurable via global settings. See #52.
