2.0.4.2

• Issue 1168 - Added lightning:accordionSection component.
• Issue 1169 - Fixed a parser issue with {! in HTML/XML comments in Visualforce/Lightning.
• Fixed an issue with proper language injection for {!...} formulas in HTML/XML string literals. This seems to be a behavioral regression in IntelliJ IDEA/WebStorm as the previous implementation did work in older builds and evidently stopped working at some point recently. The new implementation should work in all builds.
• Fixed an issue that could occur during OST generation when multiple local .object files are found in the project for the same SObject type.
• Updates required for IntelliJ IDEA/WebStorm 2018.3+.
