Revert "Deny skill exercise if not enough available xp (mesilliac)."

This reverts commit 2fc79a6d0d709878025fa1f06cf2a5344098f333.

Didn't work out too well -- it turns out that this starves rarely
trained skills compared to skills that are exercised often (and
usually with empty pool before this change).

That doesn't mean the approach of a never emptying skill pool
couldn't work, but it would require more invasive changes, like
randomly denying exercise of the heavily exercised skills.
