Remember last used parameter values for "Run" during report implementation / debugging

[alexbudarov]

Environment

• Platform version: 6.8+
• Me, sitting behind the back of our support engineer while he is trying to fix "unfetched attribute" error in the groovy report.

Description of the bug or enhancement

For complex reports debugging often is done iteratively:

• (working in Report Editor)
• change band script
• press "Run"
• input all required parameters (date from, date to, select entities, ...)
• press "Run report"
• check the document or exception - it doesn't work...
• change band script
• press "Run"
• input all required parameters (date from, date to, select entities, ...)
• ...

It's quite tedious to input the same parameter values every try.
Can we improve user experience in this situtation and remember previously entered parameters?

I'm not sure how exactly it should work, because:
a) parameter specifications can change between test runs
b) sometimes user may mean to see "clean" input parameters dialog how it usually looks

E.g. it could be an additional button on bottom pane.
