Dictionary key-editing popup buttons do nothing

[Timur Sufiev]

'Save'/ 'Cancel' buttons in dictionary key-editing popup are not actually connected to any functions on the scope, hence clicking them doesn't produce any effect. Key-editing popup behaviour should be changed:

1. Change the value of a specific key once 'Save' button has been clicked (in case new key value is valid).
2. Close the popup once 'Save'/'Cancel' has been clicked.
3. [optional] Use the popup directive from angular-bootstrap to make things simpler.

    Rewrite <editable> directive

    Instead of showing popup for the value being edited it now allows
    editing the same value in-place, accompanied with 2 buttons - confirm
    & reject the edit. Only when one of 2 these buttons is pressed (or
    equivalend Enter/Esc keys are pressed) the value will be applied. The
    <editable> directive could be used both for changing Action/Workflow
    entity names, for changing dictionary and varlist keys.
