DI getter methods suffix handling

[emulgeator]

Currently all the Dao, Table, Bo and Helper getters are waiting for the name of the entity only without the suffix. For example instead of getBo('VideoBo') it works like getBo('Video'). This is reasonable for several reasons but makes it impossible for the IDEs to follow class name refactorations in these strings as well. These getters should accept the parameters with or without the suffix

This is probably not a breaking change, and we could backport this to 0.3 as well
