T-Rex 0.18.7

Bug fixes:

• (API, Web UI) Miner crashes when changing intensity on the fly
• (ethash, kawpow, progpow) Worker name is not being passed for some mining pools From now on the username (-u) for these algorithms is no longer parsed as <wallet_address>.<worker_name>. If the pool requires the worker name to be sent, it has to be set with -w parameter. If -w is not set, the miner will set it to <algorithm>_worker0 by default.
