assigned categories to all blocks without any

[donludovico]

Hello,

in http://lists.gnu.org/archive/html/discuss-gnuradio/2014-12/msg00133.html I was told that it might be appreciated, if I added categories to GRC blocks, which actually have no assigned one. Thus, I submit a pull request, which assignes categories to blocks, which previously had no assigned category.

The change log in detail (pattern: block name -> new category - reason):

• AGC (BAZ) -> Level Controllers - like gr-analog AGCs
• Variable Delay -> Misc - like gr-blocks::delay
• Message Callback -> Message Tools - like gr-blocks::message_sink
• Message Relay -> Message Tools - like gr-blocks::message_sink
• Swap -> Misc - no better idea
• TCP Sink (Baz) -> Networking Tools - like in-tree-module(gr) of equal name
• TCP Source (Baz) -> Networking Tools - dto.
• UDP Sink (Baz) -> Networking Tools - dto.
• UDP Source (Baz) -> Networking Tools - dto.
• XMLRPC Server (Baz) -> Misc - like in-tree-module(gr) of equal name
• MPSK Receiver (Debug) -> Debug Tools - no better idea

BTW: neither baz_gat.xml nor usrp_simple_source_x.xml are not shown in GRC (I don't know the reason)
