Fixes#2953
This is an attempt to fix the issue with precipitation amount and
percentage mixup. I have created a separate
`precipitationPercentage`-variable where the probability of rain can be
stored.
The config options now has the old `showPrecipitationAmount` in addition
to a new setting: `showPrecipitationProbability` (shows the likelihood
of rain).

### Yr
I tested the Yr weather provider for a Norwegian city Bergen that has a
lot of rain. I have removed properties that are irrelevant for this demo
from the config-samples below.
Config:
```js
{
module: "weather",
config: {
weatherProvider: "yr",
type: "current",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
},
{
module: "weather",
config: {
weatherProvider: "yr",
type: "hourly",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
},
{
module: "weather",
config: {
weatherProvider: "yr",
type: "daily",
showPrecipitationAmount: true,
showPrecipitationProbability: true
}
}
```
Result:<br/>

Code updates to support a new weatherobject element called precipitationUnits. For the 'forecast' and 'hourly' UI, the weather module will use this new element if it is not null (i.e. a provider has pushed some value into this object element). If the element is null, then default 'units' processing will still occur. This allows a provider to have a customn unit of measure for precipitation - e.g. Env Canada will use mm for rain and cm for snow.
