[Ml-yokadi] How about remove project name from t_edit ?

[Sébastien Renard]

Hello,

Everything is in the title ;-). The rationale are :
- we already have a t_project command
- it's confusing to have the project name in t_edit. If you forgot your 
project name you can take it for the first word of task title.
- a vip user ask for it :-)

This issue is more visible since we remove : after project name.

Ok for that ?
