Remove todos and clean up code.

Nice job @rodedzats, seems like you finished cleaning up your TODOs.

[yonzarecki]

Remaining TODOs in the server's code, I'm tagging whoever is written as this file's author to hopefully fix this.

• [x] DBUpdater.java - @ZivIzhar

• [x] StackSearch.java - @AmitOhayon

• [x] StackOverflowPost.java - @tonylekhtman

• [x] DataBaseSomethingRenameMe.java - @tonylekhtman

[tonylekhtman]

StackOverflowPost is also under my work

[yonzarecki]

Blocked by #76 for StackOverflowPost.java and DataBaseSomethingRenameMe.java

[yonzarecki]

Any progress on StackOverflowPost.java and DataBaseSomethingRenameMe.java TODOs ? @tonylekhtman

[tonylekhtman]

These classes are going to be deleted soon anyway. We are redesigning the DAL as discussed in #102 as suggested by the ideas of @AmitOhayon

[yonzarecki]

Closing as this seems to be under control in #102
