Add a "push to a given subreddit" command

[beorn-]

It would be great to add a new command set that would work like that:

query commands:

• set a reddit account (create/update account)

  <foobar> reddit account set myaccount login password
  or
  <foobar> reddit account set myaccount apikey
  then it would answer
  <bonzbot> account myaccount (created|updated)
  

• delete a reddit account

  <foobar> reddit account delete myaccount
  then it would answer
  <bonzbot> account myaccount deleted
  

• show reddit account list

  <foobar> reddit account list
  <bonzbot> Account list:
  <bonzbot>   - reddit myaccount loginname
  <bonzbot>   - reddit myaccount loginname
  

• add a subreddit linked to a reddit account

  <foobar> reddit add myaccount /r/devel #mychannel 
  <bonzbot> subreddit output added
  

• delete a subreddit linked to a reddit account

  <foobar> reddit delete myaccount /r/devel #mychannel 
  <bonzbot> subreddit /r/devel deleted from myaccount
  

channel #mychannel commands:

• push a new tagged link to a given subreddit

  <foobar> !reddit push /r/devel httplink tag1,tag2,tag3 description
  

• shows last n links

  <foobar> !reddit latest  n /r/devel
  <bonzbot>  link#1 tags description
  <bonzbot>  link#2 tags description
  [...]
  <bonzbot>  link#n tags description
