Facade blinds

[klew]

Facade Blinds (FB) are on "Relay" channel type - the same as Roller Shutter (RS).
There is a new function for FB and "bit function" variant:

#define SUPLA_CHANNELFNC_CONTROLLINGTHEFACADEBLIND 900 
#define SUPLA_BIT_FUNC_CONTROLLINGTHEFACADEBLIND 0x00010000

Configuration is similar as for RS with following changes:

• there is no "bottom position"
• there is no "opening/closing sensor" (too be confirmed)
• new configuration option for "facade blind type" with values:

#define SUPLA_FACADEBLIND_TYPE_STANDS_IN_POSITION_WHILE_TILTING 1
#define SUPLA_FACADEBLIND_TYPE_CHANGES_POSITION_WHILE_TILTING 2
#define SUPLA_FACADEBLINE_TYPE_TILTS_ONLY_WHEN_FULLY_CLOSED 3

• new option "tilting time ms"
• new option "motor upside down" (inverts relays) (this will be also for RS, however only for channels with "runtime channel config flag set")
• new option "button upside down" (inverts buttons) (this will be also for RS, however only for channels with "runtime channel config flag set")
• new option "additional time margin" (-1 - device default, 0 - disabled, >0 % of opening/closing time added on extreme positions) (this will be also for RS, however only for channels with "runtime channel config flag set")
• new option "tilt 0 angle"
• new option "tilt 100 angle"

Tilt 0/100 angle - device reports tile in 0-100 value. User defines the corresponding angle for values 0 and 100, so that Cloud and App may calculate and show to user tilt in degrees (instaead of 0-100 % value).

Tilt angle should be visible to user (next to closing procentage) and in API/direct links etc.

Channel config definition for facade blinds: https://github.com/SUPLA/supla-core/blob/17eca0473cad20944faf331cc7951c2890858c1c/supla-common/proto.h#L2688

FB should support the same actions as RS. Only "open partially" and "close partially" should have additional tilt setting (angle value in range tilt 0 and 100 angle parameters).
