Add "hostname" condition to Conditional includes (`includeIf`)

[Diogo-Rossi]

Related to: #233

This is a more specific request to add a new conditional include keyword in includeIf conditions that matches the hostname.

A common usage would be for dotfiles, for which the current approach using git requires separate branches and rebase.

Example:

[includeIf "hostname:FIRSTMACHINE"]
	path = /path/to/firstmachineconfig.inc
[includeIf "hostname:SECONDMACHINE"]
	path = /path/to/secondmachineconfig.inc
