Add `ckp edit` command

[elhmn]

The ckp edit <script_sha> command is taking a script sha as argument which is stored in a file as an ID

The user can provide the informations required to edit his scripts or solution by sending them through flags such as

• --alias | a
• --comment | -m
• --code | -c
• --solution | -s

ckp will remove the old_script entry and replace it with a new one containing the current newly edited data
