TypeScript & TS/JS React: improve types detection, fix float-points & other improvements/fixes

Summary:

Changes:

TypeScript:

• Don't highlight built-in classes as functions. For example:

let a = Array(12);

• Fix highlighting of floating points: the rules for detecting floating point aren't in correct order, so numbers like 1.E+3 aren't highlighted correctly.
• Improved type detection, for example:

hello<string>
let d: string = "hello";
let a: null = null;

In that example, string will be highlighted as "Type/Primitive" only after : and between < and >. In the third line, the first null will be highlighted as "Type/Primitive" and the second null as "Keyword".

TypeScript React:

• Adapt to the the changes of typescript.xml.

TypeScript React & JavaScript React:

• Allow type assertion in the tag name, for example: <C<number> />
• Allow tags after the keywords await & yield.
• Allow empty tags: <></>.
• Allow Non-ASCII characters in component tags.
• Allow inserting code anywhere in a tag. Example: <tag b="hi" { code } />
