* addClockEvent - allow TimerSeconds
* Clean up tests
* Fix string tokenizer GetArgFrom when multi expand
When TOKENIZER_ALTERNATE_EXPAND_AT_START flag is set, the Tokenizer_GetArgFrom will return strings that are not aligned with the appropriate argument, this change attempts to fix that.
In addition multi expand is enabled in the addClockEvent function to allow the following commands:
```
addClockEvent $CH4:$CH5 0xff 5 echo ExpandedTimeString
addClockEvent $CH4*3600+54*60+59 0xff 5 echo cCculateTimerSecondsFromExpression
```
* Revert a function delete
* Get the next sunset or sunrise values as TimerSeconds to allow setting a light's initial sate.
* Fix BL602 & W600 builds, and add some self test asserts for get sunrise/sunset
* Clock based self tests fail if they are not run in Europe time zone.
Update all usages of localtime to be gmtime. On windows local time is has the timezone applied on top of the sourceTime parameter, OpenBK app manages its own timezone and applies it to g_ntpTime appropriately, so gmtime will avoid the additional timezone application on windows machines.
* Simplify sample autoexec to avoid functionality that has not been implemented yet.
* Update docs
* Small fix in autoexe file
No brackets allowed, multiplications before addition appears to work
