Content assist for CamelCase and Underscore

You can quickly filter the proposals list by using capital letters or underscores as anchors like the the examples below:

Variable Name	Substrings that do find variable	Substrings that don’t find the variable
uvmTestDoneObjectionBase	uTesDonObj, DoneObj, TDOB	estDone, tionBase
uvm_test_done_objection_base	uv_te_d_o_b, t_d_o, TDO	ne_objection
uvm_TESTDone_objectionBASE	uv_T_D_o_b, test_done_objection_base, TESDOB	ESTDone_, one_objection

Natural behavior with ignore case turned on or off.
