Should fix#460. I'm unable to reproduce it myself, but the stack trace shows the crash occurring on the edited line, likely because `prop` is null. This fixes that by adding a null check before using `prop`.
* Expose more private values of Solution and SolutionComponent
Expose SolutionComponent.ContainedSolution and Solution.Contents. Both needed by ReagentDispenserComponent.
* Implement IExamine for SolutionComponent
Allows players to see the contents of a solution by examining the entity which contains it.
* Implement ReagentDispenserComponent
Adds ReagentDispenserComponent. A component which can add or remove reagents from a solution container. It's written in a general way so that it can be used for things such as the Chemical dispensers in chemistry, but also the booze and soda dispensers in the bar.
The chemicals it may dispense are defined in yaml, similar to the way that vending machines define which entities they can dispense, by defining a reagent pack.
* Add chemical dispenser and equipment
Adds the chemical dispenser, beaker, large beaker, dropper, and a few more chemicals.
* Add booze and soda dispensers.
Adds the booze and soda dispensers, and a few chemicals for them to dispense. There's no drink mixing or drunkenness yet.
* Update engine submodule.
* Remove unneeded and commented out code
Had a few WIP notes and debug code bits I forgot to remove beforehand.
* Make SolutionComponent._containedSolution and it's values private again
- Remove `SolutionComponent.ContainedSolution` property, replace with specific access functions to maintain safety.
- Make Solution.Contents return a `ReadOnlyCollection` instead of `_contents` to prevent uncontrolled access to the Solution values.
- Add `SolutionComponent.RemoveAllSolution()`
* Update Content.Shared/Chemistry/Solution.cs
Commits a suggestion from RemieRichards to match the coding style of the rest of the codebase. Using `IReadOnlyList` instead of `IReadOnlyCollection`.

* Add import for IReadOnlyList to Shared/SolutionComponent.cs
* Add documentation
* Improve localization
Improve use of ILocalizationManager.
* Resolve ReagentDispenserWindow._localizationManager before using it
Forgot to do this in the last commit, resulting in a crash. Oops.
* Add SolutionCaps.FitsInDispenser. Use in ReagentDispenserComponent.
Used to limit large containers like buckets or mop buckets from being placed in a dispenser. Both have large capacities (500) and weren't designed to hold certain chemicals like a beaker is, so for now they can be blocked from being put in a dispenser by giving them that flag.
* Add colors to new reagents
* Update engine submodule
