Citrus Functions documentation gaps

[picimako]

Hi!

I've been going through the implementations of Citrus function classes and I've found a few things that are missing from the documentation on the website:

• encodeBase64/decodeBase64: no mention of the optional charset parameter.
• readFile: no mention of the optional encode base64 and replace dynamic content parameters.
• jsonPath: no mention of that the jsonPath expression is always the last parameter, and there can be an arbitrary number of json source part parameters before that, that are concatenated into a single json source text.
• unixTimestamp: there is no section for this in the documentation

hello @picimako, thanks for the remarks. contributions are always welcome, if you're able to do so. especially in the documentation section - we're always having hard times there. please let me know if you're willing to do so, or if I should proceed with the updates if I find time.

@bbortt Yeah, I'll do it gladly.

Fixed with #1088
