XNet Gases

• Fixes #3. API changes to XNet.

Requires RFTools Base >=2.0.8 and XNet >=3.0.10

Added support for Mekanism slurry to a new channel type called "mekanism.slurry". Issue and commit

Logic channel for slurries and gases. Feature request

• 1.15 Mekanism mixes slurries into gases, so technically its only for gases.

• Fixes #3. API changes to XNet.
• Slurry feature does not need to be ported from 1.16 as Mekanism 9 still used the Gas API for that.

Requires RFTools Base >=1.1.9 and XNet >=2.1.14
