fix(queries:properties): proper numeric values

[Rudxain]

Changes:

• swap the precedence of float and integer so that integer has a chance to match. Previously, only float could match a value, because of its order and broadness
• allow "+" as an optional prefix
• allow empty integer part for floats (yes, -.1 is valid!)
• fractional part can be arbitrary length
• allow exponent for floats
• allow unsigned hex integers

Unresolved questions:

• should underscores be allowed?
• should \d+. be considered float?
• should infinity be considered float? if so, case-sensitive?

Important

The Java spec says "yes" to the first two, but that would make the regexes more complex, and I haven't fully tested it

Questions that I've answered to myself:

• should hex floats be allowed? I'd say no, that's just too much
• should NaN be a float? absolutely no, who would need that?
