perf: Improve performance of toTitleCase, register with lower and tit…

[brandonocasey]

ToTileCase is one of our biggest startup functions, taking about 12ms to run. This pull request speeds that up by:

1. Making the toTitleCase function faster
2. Adding a toLowerCase function so that we can register title and lower case tech names
3. Since we register both title and lower case tech names, we can omit toTitleCase in most common scenarios

with all this done toTitleCase + toLowerCase take about 0.6ms combined!

Do we need any additional tests for getChild/registerComponent?

[gkatsev]

so, basically, this is the big gain here? Because we register the component both as component and as Component, we can just assume it'll be available and we don't need to toTitleCase the name?

[brandonocasey]

exactly!

[gkatsev]

Is this needed? The behavior related to this isn't changing. Same with line 484.

[brandonocasey]

We need this because, getChild used to toTitleCase the name that it was given. Now we won't do that because we register both possible names during addChild.

[gkatsev]

oh, didn't realize that getChild used this property. However, it sounds like we don't need to call toTitleCase again because it sounds like componentName is always toTitleCased per lines 430 and 388. So, we would only need to register the toLowerCase version.
