This commit introduces an option to control the way components are pushed into the stack.
When pushing components into a stack, they are pushed the moment they are measured.
If `waitForRender` is true, components will be pushed only after the initial render.
api:
```js
options: {
animations: {
push: {
waitForRender: true
},
showModal: {
waitForRender: true
}
}
}
```
