Calculate in configs

[Phibedy]

Calculate in configs,

<config>
 <a>6*4+7</a>
 <a>6^2+7</a>
<fancy>4rad*20degree</fancy>
<awesome>5m+3cm+4mm</awesome>
<legendary>5m*3cm + 2m^2</legendary>
</config>

The framework would calculate in SI-units and rad

Units to convert:

• Time (SI: seconds): us, ms, s, h, m
• Distance (SI: meter): mm, cm, m
• Angle (SI: radiant): rad, deg

We could also add some constants: https://en.wikipedia.org/wiki/Physical_constant

• pressure hPa, bar, mbar etc.
• percent %
• temperature grad,
  We could also add a unit-tag. For example

<a unit="mbar/K*J>5cm</a>

We should remove lconfs
