Implement timetrace edit record command

[dominikbraun]

Just as projects are editable via timetrace edit project, records should be editable using timetrace edit record. The command syntax should look just like the syntax of timetrace get record:

timetrace edit record [options] <YYYY-MM-DD-HH-MM>

• Running edit without any options should open the default editor to directly edit the record file (see edit project).
• Running edit with options should load the record internally, apply the option values and save the record. The supported options are explained below.

Command options

Flag	Short	Type	Description	Example
--plus	-p	String	Adds the given duration to the end time of the record.	--add 10m
--minus	-m	String	Substracts the given duration of the end time of the record.	--minus 10m

Those options probably aren't too hard to implement if the durations can be parsed as time.Duration. In that case, calling something like record.End.Add(plus) should be sufficient.

An open question would be how --plus operations are handled if the calculated end time lies within the timespan of another record.
