New commands from #apertium

Hello,

Firstly, we experienced some issues with the title response part of phenny. (i.e. when a user sends a link, phenny responds with the title of the link). There are five commits in here that fix `405: Method Not Allowed`. Sorry about the sheer number of those commits, blame my testing ability :tongue: 

Fixes/Updates:
* `.time`- seemed to be around from an older version of phenny. 00e1a1a
* `.seen`- ditto. Also, we added a "time since" part in the response. e710e63
* `.tell`- now, if you put `**pm**` in a .tell, the message is sent privately. 88b2e39
* `.wik`- command can now also be `.wik.<lg> <query>`, to search the given language's wikipedia. defaults to English. 40ed3de
* The apertium-related tasks 390c939

Additions:
* `.t <phrase> <lg1-lg2>`- Use apertium to translate phrase from lg1 to lg2. `.listlangs` gives the available languages 60cb026 and 490ad82
* `.botslap`- tell phenny (s)he's being bad 7424f42
* `.py <code>`- run python2 code (executed on online sandbox)  59cad85
* `.ethnologue <lg>`- language information lookup 9501389
* `.follow <user> <lg1-lg2>`- get pm'd translations of what the user says from lg1-lg2. 787ffa3
* github.py and svnpoller.py- various commands for github repo management. phenny will say when there are new pushes if a post-commit hook is written. 373cae0 and c1032c2
* `.iso639 <lg>`- language code lookup. requires ethnologue.py a123d4c
* `.lmgtfy <user> <query>`- let me google that for you 96763ad
* `.fight <user>`, `.hug <user>`- ba3494f
* `.wikicount <lg>`- find how many articles a given wikipedia has 11379ee
* `.ety <word>`- find the etymology of a word. e37d6e2
* `.whereis <user>`- if the user left an away message with `.away`, get it. e26e877
