Apex Editor - Make use of the IntelliJ IDEA feature of code folding for all curly braces delimited code blocks, not methods only

[Michal Zaganczyk]

It would be very nice to have in Apex Editor the code-folding feature that IntelliJ IDEA gives for all code blocks delimited by curly braces (like if / else / for / while / try / catch / finally statements). Currently in Apex Editor it works on method-level only.

For Java it works very nice - for example: if you have the cursor inside the "if" statement and press Ctrl+Shift+period, this "if" statement is folded, Ctrl + period will unfold it back.
