Changing terminal name in config.json for better usability

[Alex5434]

Is your feature request related to a problem? Please describe.
The current terminal name is "xterm-color", it works fine but when i use commands like "htop" the mouse clicks and scrolls are disabled.

Describe the solution you'd like
By changing the terminal name to "xterm-256color" it support for 256 colors enabled and also solves this mouse problem.
