The current charge mode of the controller should also be available via mqtt

[alxbauer]

It would be great to get the current charge mode "Absorb, Float etc." via mqtt.

E.g. in the "status" Topic.

[stuartpittaway]

Two new values are published over MQTT status message - chgmode and chgtimer.

chgmode = integer for charging mode =     
   standard = 0,
    absorb = 1,
    floating = 2,
    dynamic = 3,
    stopped = 4

chgtimer = number of seconds remaining in the current mode (for absorb or float only)
